Le'Veon Bell practices for Steelers

PITTSBURGH – The banged-up Steelers got some good news on the injury front on Wednesday.

Le’Veon Bell practiced less than a week after the rookie running back sustained a concussion, and he is on track to play Sunday assuming he doesn’t suffer any setbacks.

Bell and offensive tackle Mike Adams (ankle) were among the injured Steelers players who practiced fully on Wednesday.

Three starters did not practice while another one, defensive tackle Brett Keisel, has already been ruled out for Sunday when the Steelers host the Dolphins in a 1 p.m. game.

Left tackle Kelvin Beachum (knee), right guard David DeCastro (foot) and nose tackle Steve McLendon (ankle) all missed the Steelers’ first practice of the week. Beachum and DeCastro are questionable for Sunday and if they don’t play the Steelers will have three new starters on their offensive line.

Cody Wallace will make his first career NFL start, taking over for Fernando Velasco, who is out for the rest of the season with a ruptured Achilles tendon. Velasco was at the Steelers’ practice facility Wednesday getting medical treatment.

Outside linebacker LaMarr Woodley was the Steelers’ only limited participant in practice.

Woodley is trying to come back after missing the last three games with a stained calf.
