The Bills placed OT Chris Hairston on the Reserve/Non-Football Illness list on Monday.

Hairston missed a good portion of OTAs and all of training camp with a lower body injury that had him moved to the Active/PUP list earlier this year. Hairston had been working with athletic trainers on the side at practice daily but did not make enough progress to be elevated.

The team’s roster now stands at 75 as the NFL granted a roster exemption for FS Jairus Byrd.
