Steelers coach Mike Tomlin confirmed the team is "looking to add at least one" additional wide receiver and quarterback, and they worked out quarterbacks Brian Hoyer and Mike Kafka and wide receivers Plaxico Burress and training camp participant Derrick Williams Tuesday.

Tomlin stressed the players the Steelers are looking to bring in are deep roster depth additions, not players they expect to play in Week 12. He did not rule out the return of WR Antonio Brown in Week 12, so he isn't looking for a marquee player or special teams contributor.

He noted WR Jerricho Cotchery "fractured multiple ribs" against the Baltimore Ravens in Week 12, and while he didn't list a time frame for recovery, Tomlin noted he doesn't expect

"Plax is in really good physical condition from the workout I just saw," Tomlin said. "And obviously, he knows football."

Tomlin also said QB Byron Leftwich fractured multiple ribs, but speculated the last sack Leftwich took could have been the one that caused the broken ribs. Tomlin chuckled a little bit mentioning Leftwich injured his shoulder on his touchdown run on the Steelers' first possession, but did not stray from his conviction that Leftwich was hurt late in the game.

In saying he doesn't see the injuries to Cotchery and Leftwich being season-ending, it would mean the Steelers will release two players heading into Week 12 - assuming the Steelers do sign one wide receiver and one quarterback.

The name unmentioned as far as free agent workouts so far is Williams. It's possible Williams is working out for a practice squad spot, meaning a third candidate is rookie WR Toney Clemons, who's currently on the Steelers' practice squad - as is WR Derek Moye.
