Knox (groin) returned to practice Monday, Alaina Getzenberg of ESPN.com reports.
Knox's absence Sunday was chalked up to "groin/vet rest," and this would seem to confirm it's nothing serious. He should still have a role in the Buffalo offense as a regular blocker and occasional pass catcher, but he isn't likely to see as many targets as he did from 2019 to 2022 now that the Bills have 2023 first-round pick Dalton Kincaid at tight end.
