The 24-year-old Bills safety was taken to the University of Cincinnati Medical Center, and the Monday Night Football game was postponed.
The Jan. 2 Monday Night Football game between the Buffalo Bills and the Cincinnati Bengals was called off after Bills safety Damar Hamlin suffered a horrifying injury. He remained sedated and was listed in critical condition early Tuesday.
The 24-year-old made a tackle on Bengals player Tee Higgins at 5:55 p.m. PT. After the play, he stood up briefly before falling backward onto the turf. Hamlin was given immediate medical attention on the field, including CPR. After being taken to the University of Cincinnati Medical Center by ambulance at 6:25 p.m. PT.
Later Monday, the NFL announced that the game would be postponed for the evening.
Hamlin's tackle on Higgins occurred with six minutes to play in the first quarter. The impact seemed to land right in Hamlin's chest and neck area but he was able to stand briefly after the play was over. He was barely able to take a step before he then collapsed to the ground. Medical staff were immediately at his side. Announcer Joe Buck noted during the ESPN broadcast that medical personnel were "really pounding on his chest" as they administered CPR.
Players from both teams were clearly distraught in the wake of the injury and formed a wall around Hamlin, the local paramedics and medical staff. Teams were originally told there would be a five-minute break in play but returned to the locker rooms. The NFL called the game off shortly after 7 p.m. PT.
A further update was provided by Jordon Rooney, an associate of Hamlin, who noted that Hamlin's vitals were back to normal in a tweet posted at 7:32 p.m. PT.
The Buffalo Bills confirmed Hamlin suffered a cardiac arrest following the first-quarter hit, noting his heartbeat was restored on the field.
In the wake of the injury, fans have been contributing to a GoFundMe established by Hamlin and the Chasing M Foundation for a toy drive, leaving messages of support. The fundraiser has accumulated more than $3.7 million since Hamlin left the field of play on Monday.
