Damar Hamlin was admittedly a bit nervous when he stepped onto the Buffalo Bills’ practice field on Monday.

But by the end of the practice, Hamlin’s first with pads at training camp, things were back to normal — which is something that, after his terrifying collapse during a game earlier this year, felt like it may never come.

Hamlin was hit in the chest and went into cardiac arrest during the Bills’ game against the Cincinnati Bengals on Jan. 2. His heart stopped and he lost consciousness while emergency personnel tended to him. He was down for about 15 minutes in what was a terrifying scene before he was transported to a local hospital.
