PITTSBURGH -- Right arm tucked into a black sling, weary eyes betraying a lack of sleep, Ben Roethlisberger tried to stay positive after the worst -- and by far the most harrowing -- injury of his career.
The Pittsburgh Steelers quarterback believes he can return this season despite spraining his right shoulder and suffering what he called a dislocated rib in Monday night's overtime win against Kansas City.
He's just not sure when he'll be ready. And his medical team appears nowhere close to figuring out how exactly to get him there.
"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."
All Roethlisberger knows for certain is that doctors are concerned the rib -- which he injured while getting sacked by a pair of Kansas City linebackers in the third quarter on Monday -- could puncture his aorta if jostled around.
Foles ready to replace Vick
PHILADELPHIA -- Nick Foles officially remained No. 2 on the depth chart, even as he talked like a starter.
Facing a crush of media in front of his locker, Foles sounded every bit like the Philadelphia Eagles quarterback who will make his first career start Sunday at Washington, not an injured Michael Vick.
"I'm ready," Foles said after running the first team Wednesday. "I'm excited to just play again. Like I said before, my prayers are with Mike, I just want Mike to be healthy. But it's my time to go out there and just play and do everything I can for this team ..."
Vick's status atop the depth chart is a mere formality. He did not practise or even come to the Eagles' practice facility again Wednesday as he recovers from a significant concussion suffered in last week's loss to Dallas.
Murray has 'a chance'
IRVING, Texas -- Dallas coach Jason Garrett keeps talking about "thresholds" running back DeMarco Murray must meet to end a longer-than-expected absence because of a sprained foot.
It's probably not on the official list, but Murray offered a benchmark on Wednesday. He said there was "a chance" he could play Sunday against Cleveland.
Murray has missed four games since rushing for 93 yards in a loss at Baltimore on Oct. 14.
Pack's LB Matthews out
GREEN BAY, Wis. -- Green Bay Packers linebacker Clay Matthews will miss Sunday's game in Detroit with a hamstring injury.
Coach Mike McCarthy says the absence this week was expected. Matthews was hurt in the second half of Green Bay's Nov. 4 game against Arizona, and McCarthy said the next day that the three-time Pro Bowler would miss a couple of weeks.
"This will be his second week," McCarthy said. "We'll see what happens next week."
Matthews is tied for second in the NFC with nine sacks.
