McNichols (hamstring) was a full participant in Thursday's practice, Jim Wyatt of the Titans' official site reports.
McNichols' reps were capped Wednesday in the Titans' first Week 5 practice, but his return to full activity a day later puts him on track to play Sunday in Jacksonville. Assuming Tennessee waits at least one more week to activate Darrynton Evans (knee) from injured reserve, McNichols should be on track to fill his usual change-of-pace role behind Derrick Henry on Sunday.
