PITTSBURGH — Ben Roethlisberger has a sprained right shoulder. When the two-time Pro Bowl pick will be ready to play again is anybody's guess.
Coach Mike Tomlin called Pittsburgh's franchise quarterback "questionable" Tuesday but otherwise offered little detail. Monday, Roethlisberger was pounded into the ground by Chiefs linebackers Tamba Hali and Justin Houston in the third quarter of Pittsburgh's 16-13 overtime victory.
"He is being evaluated," Tomlin said.
Roethlisberger left the game and went to the hospital for an MRI exam. He had more tests 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.
If he can't play Sunday against the Ravens, backup Byron Leftwich will play, as he did Monday after Roethlisberger left.
Steelers safety Ryan Clark also sustained a concussion, the Pittsburgh Tribune-Review reported.
PETERSON CHARGE DISMISSED: A grand jury in Houston dismissed a misdemeanor resisting arrest charge against Vikings running back Adrian Peterson after hearing from the four-time Pro Bowl pick and other witnesses. Derek Hollingsworth, one of Peterson's attorneys, said the case is expected to be formally dropped today.
BEARS: With Jay Cutler's status uncertain after a concussion, the team signed veteran backup quarterback Josh McCown.
CHIEFS: Coach Romeo Crennel said he plans to speak to his team about discipline issues in Monday's loss, including one instance in which Kansas City was flagged 15 yards for a group celebration on a touchdown that wound up being reversed on replay. "It was a surprise to me," Crennel said of the sudden celebration.
FALCONS: Tight end Tommy Gallarda (shoulder) went on injured reserve and the team signed wide receiver Tim Toone and tight end Chase Coffman.
JETS: Newsday reported that linebacker Aaron Maybin, a former first-round draft pick in Buffalo, was waived.
PATRIOTS: They signed guard Mitch Petrus, who played six games in 2012 with the Giants.
VIKINGS: Minnesota Gov. Mark Dayton criticized the team for considering extra fees on season tickets to help cover the team's share of a new $975 million stadium. Team owners said that option was a key part of the deal.
