PITTSBURGH (AP) - Ben Roethlisberger left Heinz Field on Monday night with his sprained right shoulder in a sling. When he walks back in ready to play is anybody's guess.
Tomlin called Pittsburgh's franchise quarterback ``questionable'' but otherwise offered little detail Tuesday, less than 24 hours after Roethlisberger was pounded into the ground by Kansas City Chiefs linebackers Tamba Hali and Justin Houston in the third quarter of Pittsburgh's 16-13 overtime victory.
``He is being evaluated,'' Tomlin said. ``Obviously this injury puts his participation in the questionable category for this week.''
Roethlisberger left the game and went to the hospital to for an MRI-exam. He underwent more tests on Tuesday to determine the severity of the sprain to the sternoclavicular (SC) joint in his throwing shoulder.
The SC joint connects the collarbone to the sternum. Treatment can range from a few days of rest and ice to as much as 4-6 weeks according to Dr. Victor Khabie, chief of sports medicine at Northern Westchester Hospital in Mount Kisco, N.Y.
``You could tape it, you could do that stuff but the reality is those ligaments just have to heal,'' Khabie said. ``If you go throwing, you slow down the healing process.''
Roethlisberger was scrambling in the pocket to buy time on Pittsburgh's first possession of the second half when Houston wrapped up Roethlisberger's legs and Hali slammed into him, driving the quarterback's right side into the damp Heinz Field turf. Roethlisberger didn't appear to be hurt walking off the field but quickly made his way to the locker room before leaving the stadium with the game still in progress.
``It didn't seem like a tough hit ... but he came to the sideline and next thing you know he was gone,'' Pittsburgh left tackle Max Starks said. ``I'm hoping it was nothing serious. Honestly it didn't seem like it.''
If Roethlisberger can't play, the Steelers (6-3) will turn veteran backup Byron Leftwich, who completed 7 of 14 passes for 73 yards in relief as Pittsburgh won its fourth straight game thanks to Shaun Suisham's 23-yard field goal 51 seconds into the extra period.
The 32-year-old Leftwich hasn't started a game since 2009, when he went 0-3 for the Tampa Bay Buccaneers. His last victory came on Oct. 8, 2006 when the Jacksonville Jaguars beat the New York Jets 41-0.
The former first round pick has spent most of the last six years as a backup while dealing with a series of significant injuries. He missed all of last season after breaking his arm in a preseason game and threw seven regular season passes in 2010 after hurting his knee at the end of training camp.
Though there was a bit of rust after getting pressed into service, Leftwich did guide the Steelers to a go-ahead field goal in the fourth quarter.
``I try to prepare as if I am the starter every week,'' Leftwich said. ``Nothing will change. I wish Ben the best. I hope he is healthy. Other than that I will be ready to go.''
Leftwich insists he has mastered offensive coordinator Todd Haley's playbook and Leftwich's teammates are hardly concerned if he's under center on Sunday.
``We don't have a true rookie back there that's never taken a snap before,'' Starks said. ``We feel good about who we have back there if it is Byron. We'll move forward and wait Ben's return if that's the case.''
Roethlisberger isn't the only big name that could be out on Sunday. Safety Troy Polamalu continues to be plagued by a right calf injury and Tomlin described him ``doubtful'' to play against the Ravens. Safety Ryan Clark sustained a concussion for the second time in three games when he took a knee to the head from Kansas City wide receiver Dwayne Bowe, though Tomlin said it appears Clark is fine.
Maybe, but it's not exactly the way the Steelers wanted to be heading into a crucial three-game stretch that includes two games against the hated Ravens in three weeks.
Baltimore (7-2) appeared ready to run away with the division after Pittsburgh stumbled to a 2-3 start. The Steelers have ripped off four straight to draw within a game and can take firm control of the AFC North at home on Sunday.
The prospect of doing it without their two-time Super Bowl winning quarterback makes that task more difficult, but not impossible.
``B-Left has been here a long time,'' defensive end Brett Keisel said. ``If he's in there, we expect to keep rolling.''
