Buffalo Bills head coach Sean McDermott delivered a difficult explanation on Monday when asked why first-round rookie cornerback Maxwell Hairston was pushed to the bench for most of the team’s 26–7 victory over the Pittsburgh Steelers.

According to team sources, Hairston is still not fully recovered from concussion protocol, despite being cleared to return in a technical sense. The Bills have been desperately thin at cornerback due to multiple injuries, and Hairston — wanting to help his team — insisted on suiting up even though he wasn’t at 100%.

McDermott said the decision to reduce Hairston’s snaps was painful but necessary.

“We’re proud of how hard he’s pushing. But sometimes the body needs more time than the player wants to give it,” McDermott admitted.

In recent weeks, Hairston and veteran Tre’Davious White had been splitting snaps evenly. But against the Steelers, White played 77% of the defensive snaps while Hairston saw a drastic drop-off.

Behind the scenes, coaches were concerned that Hairston was still showing residual symptoms — slower reaction times, delayed processing, and difficulty maintaining focus in longer defensive series. Out of caution, the Bills limited him to light usage while relying heavily on White to stabilize the secondary.

Still, Hairston played because the Bills had no healthy alternatives. And even in limited action, he flashed the traits that made him a first-round pick earlier this year.

Buffalo is hopeful that Hairston will make a full recovery soon, but McDermott hinted that the team will not hesitate to sit him again if there is

any risk.

Meanwhile, the Bills await more updates on Joey Bosa, who suffered a hamstring injury after delivering the game-changing strip-sack on Aaron Rodgers. His status for Week 14 remains uncertain.

For now, the Bills walk away with a convincing win — but with growing concern that their promising young cornerback may be pushing himself too hard, too soon.
