Beachum on track to return for Steelers

PITTSBURGH -- Left tackle Kelvin Beachum was a full participant in the Steelers’ first practice of the week, and he is on track to play Sunday against the visiting Bengals.

Beachum had started eight consecutive games at left tackle before spraining his knee in a 22-20 loss to the Ravens on Thanksgiving. Coach Mike Tomlin did not commit to starting Beachum against the Bengals Tuesday at his weekly news conference. How much and how well Beachum practices will determine who protects quarterback Ben Roethlisberger’s blind side against the Bengals, Tomlin said.

Mike Adams started at left tackle against the Dolphins and played one of his best games of the season.

Less certain of returning to action this week for the Steelers is defensive end Brett Keisel.

The veteran defensive end did not practice on Wednesday, and he has played in just one of the Steelers’ last four games because of plantar fasciitis.

Also not practicing for the Steelers because of injuries were defensive end Ziggy Hood (ankle), nose tackle Steve McLendon (ankle), right tackle Marcus Gilbert (ankle) and strong safety Troy Polamalu (shoulder).

Wide receiver Jerricho Cotchery (shoulder) and right guard David DeCastro (foot) were full participants in practice despite nursing injuries.
