NASHVILLE, Tenn. -- Titans tight end Delanie Walker has cleared enough of the concussion protocol that he returned to practice Saturday in a limited fashion.
Now he must be checked by an independent neurologist before he can play Monday night against the Pittsburgh Steelers.
Walker was carted to the locker room last week after suffering the concussion late in the first half, and he had not practiced Wednesday through Friday. The Titans' leader with 512 yards receiving was limited Saturday in his return.
Coach Ken Whisenhunt says Walker will be questionable against the Steelers and must be cleared by one last doctor.
Cornerback Blidi Wreh-Wilson (back), defensive lineman Sammie Hill (hamstring) and running backs Dexter McCluster (left knee) and Leon Washington (hamstring) all were limited. They also will be questionable.
