Knox (foot/hamstring) returned to practice Wednesday, Joe Buscaglia of The Athletic reports.
Knox was unable to practice last week before being ruled out ahead of the Bills' Week 5 win over the Steelers. With his return to the field Wednesday, the tight end appears to be trending in the right direction ahead of Sunday's game against Kansas City. The Bills will release their first Week 6 injury report later Wednesday, which will reveal the extent of Knox's practice participation.
