ORCHARD PARK, N.Y. — Damar Hamlin has little more to prove to Bills Coach Sean McDermott in the third-year safety’s bid to resume his football career after a near-death experience during a game at Cincinnati in January.

“From my non-medical standpoint, I think he’s checked all the boxes as far as that goes,” McDermott said on Thursday. “There’s just been enough of a sample where you’re saying, he’s executed well and come out of that healthy.”

McDermott based his assessment on how Hamlin has showed no signs of hesitation in passing each milestone of his recovery, and especially since the Bills began practicing with pads three weeks ago. Adding to that, the coach was further reassured by Hamlin’s performance in Buffalo’s preseason-opening win over Indianapolis last weekend.

Hamlin was in on three tackles — including stopping Evan Hull for no gain on fourth-and-1 — in playing 22 defensive snaps in his first competitive setting since going into cardiac arrest and being resuscitated on the field after making what appeared to be a routine tackle against the Bengals on Jan. 2. Hamlin’s heart stopped as a result of commotio cordis, which is when a direct blow at a specific point in a heartbeat causes cardiac arrest.

Following the Colts game, McDermott called Hamlin’s performance “a remarkable display of courage and strength and faith,” while adding: “What we just witnessed, to me, is remarkable.”

McDermott’s backing of Hamlin represents the latest signal the player is on track to make the Bills’ roster and re-secure his backup spot behind starters Micah Hyde and Jordan Poyer.

The Bills have two more preseason games left, starting with a notable one for Hamlin on Saturday, when Buffalo travels to the player’s hometown of Pittsburgh.

The Bills close their preseason at Chicago on Aug. 26 before being required to make their final cuts three days later.

LIONS: Coach Dan Campbell said receiver Jameson Williams will likely miss the rest of the preseason with a hamstring injury.

Williams’ injury is another setback for the former Alabama star, who was injured for much of his rookie season and will be suspended for the first six games this year for violating the NFL’s gambling policy.

He grabbed his right hamstring while running a pass route Wednesday, left the field for treatment and did not return. He hurt his left leg earlier in training camp and missed four practices.

CHIEFS: The Kansas City Chiefs plan to play Patrick Mahomes and the rest of their starters for the first half of their preseason game in Arizona, where they were last seen walking off the field hoisting their second Lombardi Trophy in four years.
