New York Jets cornerback Darrelle Revis did not practice for the second straight day while recovering from a mild concussion sustained last Sunday.
Revis was hurt while making a tackle in the fourth quarter of New York's 48-28 win over Buffalo when he was kicked in the head by teammate Bart Scott.
The four-time Pro Bowler was cleared for physical activity on Wednesday, but is still yet to practice.
Tight end Dustin Keller (hamstring), safety LaRon Landry (heel), linebacker Bryan Thomas (hamstring) and cornerback Isaiah Trufant (ankle) also did not participate in Thursday's practice.
In other injury news, fullback John Conner (knee), wide receivers Stephen Hill (calf) and Jeremy Kerley (low back), linebacker Josh Mauga (rib), defensive tackle Sione Po'uha (low back) and safety Eric Smith (hip/knee) were all limited in practice on Thursday.
