The football-watching world has offered thoughts and prayers for Damar Hamlin, who is in critical condition after collapsing on the field during Monday Night Football. He was administered CPR before being driven away.

The Buffalo Bills safety collided with Cincinnati Bengals receiver Tee Higgins after a completion. He got to his feet, appeared to adjust his face mask with his right hand, and then fell backward about three seconds later and lay motionless.

He was driven to University of Cincinnati Medical Center.

The 24-year-old Hamlin spent five years of college at Pitt — his hometown — and appeared in 48 games for the Panthers over that span. He was a second-team All-ACC performer as a senior, was voted a team captain and was picked to play in the Senior Bowl.

He was drafted in the sixth round by the Bills in 2021, played in 14 games as a rookie and then became a starter this year once Micah Hyde was lost for the season to injury.

Entering the game, the 6-foot, 200-pound Hamlin had 91 tackles, including 63 solo tackles, and 1 1/2 sacks.

Hamlin’s charity toy drive – The Chasing M’s Foundation Community Toy Drive – has raised nearly $1 million Monday night since Hamlin’s injury.

A tweet from the Pitt football account was simple and clear: “Damar Hamlin is the best of us. We love you, 3,” the tweet said, referring to Hamlin by his college jersey number. “Praying for you.”
