OWINGS MILLS - Steelers quarterback Ben Roethlisberger practiced on a limited basis Wednesday and Pittsburgh coach Mike Tomlin indicated it's a possibility Roethlisberger could be available for Sunday's game against the Ravens.
Tomlin said Roethlisberger threw the ball "a little bit" on Monday as well.
Roethlisberger has missed each of the Steelers' last two games after suffering a sprained shoulder and rare rib injury during Pittsburgh's overtime win against the Chiefs in Week 10.
ESPN reported Tuesday that Roethlisberger has a 50-50 chance of playing against Baltimore Sunday, although a source close to Roethlisberger told the Pittsburgh Post-Gazette that he would be "shocked" if the quarterback played this weekend.
"We'll see where the week takes us," Tomlin said during a conference call with Baltimore media Wednesday.
The Steelers have dropped each of the two games that Roethlisberger has missed - falling to the Ravens, 13-10, two weeks ago and the Browns, 20-14, Sunday.
Without Roethlisberger in the lineup, Pittsburgh's offense managed just 309 yards of total offense against Baltimore and only 242 yards against Cleveland.
The Steelers' offense was averaging 354 yards per game prior to the last two weeks.
Roethlisberger threw for an average of 275 yards in Pittsburgh's first eight games. He has 17 touchdowns and just four interceptions.
In his place, Byron Leftwich and Charlie Batch have combined for just 398 yards with no touchdowns and four interceptions.
Batch was forced into action against the Browns with Roethlisberger and Leftwich (ribs) both unavailable. He was 20-of-34 for 199 yards with three interceptions.
Tomlin said during his weekly news conference Tuesday that "right now" the Steelers are preparing as if Batch will be their starter against the Ravens, but added that Roethlisberger's "got a chance" to play.
"[He] will take steps towards playing this week," Tomlin said of Roethlisberger. "We'll leave the door open for him. He's got a chance."
NOTE: Pittsburgh wide receiver/return specialist Antonio Brown (ankle) and safety Troy Polamalu (calf) were both full participants in Wednesday's practice and both are expected to be available for Sunday's game against Baltimore.
"They're going to add some players, it sounds like," Ravens coach John Harbaugh said.
Brown has missed each of the last three games. The speedy and elusive playmaker had a team-high 42 catches for 499 yards and a touchdown prior to sustaining his injury.
He was also the Steelers' primary punt returner.
"[Brown's] a playmaker on offense and special teams," Harbaugh said. "He's another factor on offense that will obviously help."
Polamalu has been sidelined for the last seven games after aggravating a calf injury in Week 5. He's played in just two games this season.
"Obviously, with Troy, you have to be aware of him at all times," Harbaugh said. "They've done a great of playing defense back there without Troy. So, you add a guy like that in the mix, obviously, what a factor that can be."
Outside linebacker LaMarr Woodley was a non-participant in Wednesday's practice. Tomlin said Tuesday that it's "doubtful" Woodley will be available against Baltimore.
