Knox (concussion) is listed as a full participant for Wednesday's practice, Maddy Glab of the Bills' official site reports.
Though Knox looks like he'll take all the reps in Wednesday's practice, he hasn't necessarily cleared the NFL's concussion protocol just yet. That said, the fact that he's beginning the week on the field is a good sign with regard to his chances of being available in Sunday's game against the Raiders. Even if Knox gets the green light to play this weekend, he may have to fight to earn some looks in the passing game after Buffalo's other tight ends combined for three touchdown receptions from quarterback Josh Allen in the Week 3 win over the Rams.
