Feliciano will miss the next 8 to 12 weeks to recover, league sources confirmed to ESPN. BuffFanatics first reported on a timeline for Feliciano.
The surgery comes six months after Feliciano underwent surgery on a torn rotator cuff in January.
Feliciano posted about his injury in an Instagram video, saying it was a "freak accident" that happened while he was working out.

Worked my butt off this offseason. Made the best home gym in buffalo. Came in 15 pounds under weight + felt stronger than I've ever been. 💩 happens. Loyalty is what drives me. The amount of support that I got from Beane, McDermott, Dabbs, OG, my teammates and #billsmafia drives me. I won't let them down. I'm coming back with a vengeance. See y'all in Vegas
Feliciano started all 16 games at right guard in his first season in Buffalo in 2019, the first time he had done so in his five-year NFL career. His absence leaves the Bills with several contingency plans, including moving second-year right tackle Cody Ford inside. Ford practiced at guard and tackle during his rookie training camp last season before starting 15 games at right tackle.
