Damar Hamlin: The Night His Heart Stopped and the Legacy He’s Creating
From McKees Rocks to the NFL
Damar Hamlin grew up in McKees Rocks, Pennsylvania, a small borough just west of Pittsburgh where football isn’t a hobby – it’s something closer to identity. He attended Central Catholic High School, earned first-team All-State honors, and was named the Class AAAA Defensive Player of the Year. Pittsburgh recruited him. So did Penn State, Ohio State, and Temple. He picked the hometown program.
At Pitt, Hamlin played safety for four years, recording 84 tackles as a redshirt sophomore in 2018 and 72 in his senior season in 2020. He was not a projected high pick. The Buffalo Bills took him in the sixth round of the 2021 NFL Draft, 212th overall, in a slot where most players never see a second contract. He spent most of his rookie year on the bench behind Micah Hyde. When Hyde tore his neck in 2022 and ended his season early, Hamlin stepped in and started. That’s where his story was supposed to accelerate.
Instead, January 2, 2023 happened.
What happened on the field against the Bengals
Nine minutes into the Monday Night Football game at Paycor Stadium in Cincinnati, Hamlin tackled Bengals wide receiver Tee Higgins after a short catch. He stood up, took two steps, then collapsed backward onto the turf. Not a fall. A full collapse, the kind that ends conversations in the press box and makes broadcasters go quiet.
The Bills training staff was on the field within seconds. CPR began almost immediately. A defibrillator was used to restore his heartbeat. At 9:23 p.m. EST, an ambulance transported him to the University of Cincinnati Medical Center. The Bills released a statement around 2 a.m.: Hamlin had suffered cardiac arrest, his heartbeat had been restored on the field, and he was in critical condition.
The game was suspended. It has never been completed. All 32 NFL teams changed their Twitter profile pictures the next day to a photo of Hamlin’s jersey with the words “Pray For Damar.” Josh Allen, who had been standing on the sideline watching the medical team work, posted: “Please pray for our brother.” Fans gathered outside the hospital. The lights at Paycor Stadium were turned blue.
His GoFundMe – a toy drive campaign for his Chasing M’s Foundation that had a $2,500 goal – received $1 million in donations within hours. It reached $8.7 million by January 12.
Nine days in the hospital
January 3: Hamlin was sedated and on a ventilator at the University of Cincinnati Academic Health Center. His uncle Dorrian Glen said he was placed on his stomach to take pressure off his lungs.
January 5: The Bills issued a statement that Hamlin had shown “remarkable improvement” over the previous 24 hours and “appears to be neurologically intact.” Trauma surgeon Timothy Pritts confirmed he could follow commands, had full feeling and control in his extremities, and was communicating by writing on paper and nodding. His first written question to the medical staff, once he understood what had happened: who won the game.
January 6: The ventilator was removed. He could breathe on his own and speak.
January 11: Hamlin was transferred to a hospital in the Buffalo area. Several days later, he was discharged. The entire hospitalization lasted nine days.
His father, Mario Hamlin, would later say: “We don’t live in fear. I watch him now the same way I did in little league football.”
Commotio cordis: what actually stopped his heart
On April 18, 2023, at a press conference at the Bills’ facility in Orchard Park, Hamlin confirmed what cardiologists had suspected since January. The cause was commotio cordis.
Commotio cordis is Latin for “agitation of the heart.” It occurs when a blunt impact to the chest lands at a precise 40-millisecond window in the heart’s electrical cycle – the moment when electrical current is moving from one side of the heart to the other. That impact doesn’t need to be especially hard. It needs to be timed exactly wrong. The result is ventricular fibrillation: the heart stops its coordinated pumping and quivers uselessly instead.
It is the third most common cause of sudden cardiac death in young athletes. The condition is 97% fatal without treatment within three minutes. Hamlin had no pre-existing heart condition. There was nothing on any prior ECG, no structural abnormality, nothing a team physician would flag. A routine hit at a specific millisecond was enough.
“What happened to me was basically commotio cordis,” Hamlin said at the press conference. “It’s a direct blow at a specific point in your heartbeat that causes cardiac arrest and 5 to 7 seconds later, you fall out.”
Byron Lee, MD, of UC San Francisco, who had written about commotio cordis as the most likely explanation within days of the collapse, noted that survival rates have improved significantly when CPR and defibrillation are initiated promptly – now exceeding 50%, compared to near zero a few decades ago. The key phrase there is “promptly.” In most settings, no one is ready. In an NFL game, the response was immediate.
Why he survived when most don’t
The Bills’ medical and training staff were on the field before the crowd understood what they were watching. CPR started within roughly a minute of the collapse. The defibrillator was deployed. Hamlin’s heartbeat returned on the field, not in the ambulance and not in the hospital – on the field, because the equipment was there and the people using it knew what they were doing.
That is not how cardiac arrest typically goes. Outside of a hospital, the survival rate for cardiac arrest in the United States sits around 10%. The gap between 10% and Hamlin walking out of a hospital nine days later comes down almost entirely to response time.
This became the central argument Hamlin made for the next two years: the care he received was exceptional, and most people – most kids playing sports at schools without AEDs – would not get it. That’s what he decided to change.
Return to the Bills: clearing the medical bar, then proving the football one
Hamlin met with three independent medical specialists in the spring of 2023. All three cleared him to return. Bills general manager Brandon Beane confirmed the clearance on April 18, the same day Hamlin announced publicly that he intended to play again.
“I died on national TV in front of the whole world,” he said at the press conference. “This event was life-changing, but it’s not the end of my story.”
He played limited snaps on special teams in 2023 before getting his first defensive action in Week 4 against Miami. In Week 3 of the 2023 season, he intercepted Jacksonville Jaguars quarterback Trevor Lawrence – his first career interception, on Monday Night Football, two years after the night that nearly killed him on that same broadcast window. He was visibly emotional after the play. So was everyone watching.
The 2024 season was when the football argument became real. With veterans Jordan Poyer and Micah Hyde both gone in the offseason, Hamlin competed for and won the starting safety job. He started 14 games, recorded his first two career interceptions, and forced a Lamar Jackson fumble in a divisional playoff win over the Baltimore Ravens. The Bills won 27-25. Hamlin was in on defense for meaningful snaps in a playoff game.
2025 was shorter. A pectoral injury in October placed him on injured reserve after five games. He did not play in the postseason. In March 2026, he declared free agency, then re-signed with Buffalo on a one-year deal.
Across 53 career games through 2025: 185 total tackles, 2 interceptions, 8 tackles for loss, 9 passes defensed, 1.5 sacks, 1 fumble recovery. Not a Pro Bowl résumé. But he’s not just a survivor playing out a feel-good story either – he earned a starting job on an AFC playoff team. Those are hard to get.
The Chasing M’s Foundation: from toy drive to $8.7 million
Hamlin started the Chasing M’s Foundation while at Pitt. “Chasing M’s” means chasing millions – his way of encouraging kids from communities like McKees Rocks to pursue their ambitions. The original purpose was practical: support his mother’s daycare and run toy drives for children in the neighborhood.
After January 2, 2023, the GoFundMe associated with the foundation became something else entirely. $8.7 million in 12 days. Dozens of NFL players, coaches, and executives donated. The foundation had to rethink its entire structure – governance, tax-exempt status, operational capacity – essentially overnight.
Hamlin redirected that capital toward the problem he understood firsthand: sudden cardiac arrest is the leading cause of death in youth sports, and most schools don’t have the equipment to respond to it. Since 2023, the Chasing M’s Foundation has donated nearly $1 million worth of AEDs to schools, community organizations, and youth sports programs. More than 3 million people have been reached through CPR awareness campaigns connected to the foundation’s work.
He also launched scholarship programs – first in Cincinnati, honoring the medical team that saved him, then in Buffalo, where he announced the Buffalo Heroes Scholarship on January 2, 2025, the two-year anniversary of the collapse, at a dinner with the Bills’ training staff. He bought his parents a house near Pittsburgh. He named that one of his proudest accomplishments since surviving.
The HEARTS Act: from GoFundMe to federal law
Hamlin partnered with Senate Majority Leader Chuck Schumer on the Cardiomyopathy Health Education, Awareness, Research, and Training in Schools Act – the HEARTS Act. The legislation creates a federal grant program through the Department of Health and Human Services to fund AED purchases in elementary and secondary schools, CPR and AED training, and the development of cardiac emergency response plans.
The Senate passed it unanimously on December 10, 2024. The House had passed it in September. President Biden signed it on December 25, 2024.
A study published in the Journal of the American College of Cardiology found that children who experience cardiac arrest in schools with AEDs are seven times more likely to survive compared to children in schools without them. That statistic was in the congressional record. Hamlin cited it repeatedly.
“I believe that every single one of them deserves the same kind of care that I had,” Hamlin said at an event with Schumer announcing the Senate floor vote. “We have a chance to be impacting the next generation. We got a chance to make history.”
The NFL’s Smart Heart Sports Coalition – formed after Hamlin’s cardiac arrest and including the American Heart Association and other major sports organizations – also pushed for the bill, alongside advocacy for all 50 states to implement emergency cardiac protocols at the high school level.
It is genuinely unusual for a professional athlete’s near-death experience to produce federal legislation within two years. Most produce a foundation, some merchandise, and awareness campaigns that fade. The HEARTS Act is a law. Schools will have AEDs because of what happened at Paycor Stadium on January 2, 2023.
Where Hamlin stands in 2026
He re-signed with Buffalo in March 2026 on a one-year deal, his sixth season with the team. The Bills added C.J. Gardner-Johnson and Geno Stone in free agency, which shapes Hamlin’s role as a depth and special teams contributor rather than a projected starter – his pectoral injury and limited snaps in 2025 factor into that. He’s 28 years old heading into the season.
His advocacy work has continued to expand. He is an ambassador for Abbott’s HeartMates program, which connects survivors of cardiac events for peer support. At the 2026 NFL Draft, he teamed up with the American Heart Association and social media health commentator Doctor Mike to set a Guinness World Record: nearly 1,300 people completing hands-only CPR training in one hour at a single location.
He has also been public about the psychological cost of the advocacy work itself. Training CPR instructors means being around dummies on the ground, simulated collapses, defibrillator pads – the props of his worst moment. “It’s traumatic just to see a CPR instruction dummy on the ground,” he told TIME in 2026. “It’s just triggering; it reminds me of the worst things of that moment. But I knew that I was helping to save lives.” He kept doing it anyway.
“I don’t want to be just known as the player who lived,” he told an NFL reporter in September 2024. “My story is still being written. I want to be known for my abilities as well.”
That’s a reasonable ask. He earned a starting job in the NFL after cardiac arrest. He got a federal law passed. He’s donated nearly a million dollars in lifesaving equipment to schools. What he wants – to be seen as a football player, not just a survivor – is probably the one thing he can’t fully control.
