Knox (wrist) remained a limited participant at practice Thursday.
Dalton Kincaid (concussion) was also limited Thursday, and the Bills' top two tight ends likely will need to practice fully Friday in order to avoid injury designations ahead of Sunday's game against the Giants. If Kincaid doesn't end up clearing the NFL's concussion protocol in time, Knox could be in store for added opportunities in the passing game, provided he suits up this weekend.
