PITTSBURGH - Steelers quarterback Ben Roethlisberger believes he can return this season after spraining his right shoulder and suffering a dislocated rib Monday against the Chiefs. He's just not sure when, and it won't be Sunday.
"From what (the doctor) said, he's trying to talk to experts because there is no case study over the exact same thing," Roethlisberger said Wednesday. "We're just trying to talk to people ... because we don't know."
Doctors are concerned the rib, injured while being sacked, could puncture his aorta if jostled. Asked if he believes the injury is season-ending, he shrugged his good shoulder.
"I don't think so. I don't know, though. I'm not a medical expert," Roethlisberger, 30, said. "I just know I'm going to do what I can to get back."
Veteran Byron Leftwich replaced Roethlisberger on Monday and will start Sunday against the Ravens.
"I'm not going to go out there and try and be Ben," Leftwich, 32, said. "We see the game differently. He's physically able to do some things that I can't do. But that doesn't mean I can't go out there and do my job."
Anonymous Tebow criticism angers Ryan
FLORHAM PARK, N.J. - Jets coach Rex Ryan said he addressed his team about anonymous quotes from players and members of the organization ripping backup quarterback Tim Tebow that appeared in New York's Daily News.
"If you're not going to put your name to it, I think that's about as cowardly of a thing there is," Ryan said after practice. "I don't want to get into specifics of what I said."
The report quoted about a dozen people saying there's no chance Tebow can overtake Mark Sanchez for the starting job because of his poor play during practice and games.
"It's never fun to hear criticism," the former Gator star said. "At the same time, it's something I've always used as motivation. You try to get stronger from it. This is something I can't control. I can control my attitude, my effort and my work ethic. Those are things that will never change based on what anybody says."
