New York Jets shutdown cornerback Darrelle Revis participated in individual workouts in the team's practice on Friday, according to New York Post beat writer Bart Hubbuch via Twitter.

Revis suffered a concussion in New York's 48-28 Week 1 victory over the Buffalo Bills, but said Thursday that he was feeling better and would leave his playing status for Sunday's game against the Pittsburgh Steelers in the hands of doctors. Head coach Rex Ryan echoed that sentiment, saying the All-Pro cornerback will not play if he is not 100 percent, and that his ultimate status could be determined as late as Saturday. His involvement in practice on Friday signals at the least that his condition is improving.

The concussion most likely occurred when Revis was accidentally kicked in the head by teammate Bart Scott, following an attempted tackle of Buffalo running back C.J. Spiller.
