Cordy Glenn has been ruled out for the remainder of the season. On Friday, the Bills placed the offensive tackle on injured reserve. 
Glenn remains under contract with the Bills, but it’s far from certain that he’ll be back in 2018. The team is likely frustrated with Glenn’s injuries that have kept him off the field for 15 games over the last two years. He’s also expensive with base salaries of $9.25MM, $7.25MM, and $7.25MM over the next three seasons, plus $2MM in roster bonuses each year. With rookie Dion Dawkins waiting in the wings, they have options.
“I’ve been impressed with the way [Dawkins] has come into the league,” Bills head coach Sean McDermott said earlier this season (via Rick Kowalski of USA Today). “His mindset, his approach, he’s an aggressive player, he really fits our personality upfront – what we want to be all about upfront and as an offensive unit. He’s bounced around, [has] played different positions. That’s been a challenge, but he’s embraced that challenge the whole way.”
If the Bills release Glenn, they can save $4.85MM against the cap by cutting the 28-year-old. Alternatively, they can put him on the trade block. Glenn drew interest from teams at this year’s trade deadline, including the Seahawks, so there’s at least some market for him, despite his health concerns and hefty contract.
