Pittsburgh Steelers running back Jonathan Dwyer is doubtful for Sunday's game against the New York Giants with a quad injury.

PITTSBURGH — Pittsburgh Steelers running back Jonathan Dwyer might not get a chance at a third straight 100-yard game on Sunday against the New York Giants.

Dwyer is listed as doubtful thanks to a right quad strain that prevented him from practicing Friday. Starting running back Rashard Mendenhall (right Achilles) is also listed as doubtful, leaving Isaac Redman and his sore ankles as the healthiest feature back on the roster.

“The good thing is that we’ve got three good running backs, so when somebody goes down we always have somebody else ready to go,” Redman said. “It’s a shame that we all can’t get healthy at the same time, but that’s what makes it crucial that we have so much depth.”

Dwyer became the first Pittsburgh back in four years to post consecutive 100-yard games when he rushed for 107 in last week’s 27-12 win over Washington. He tweaked the quad in the fourth quarter and was limited to just one day of practice this week.

“It’s all about getting wins and getting to the Super Bowl, that’s all I care about,” Dwyer said. “Sure, I want to be out there and play, so when I’m ready to go I’ll be on the field.”

While safety Troy Polamalu will miss his fourth straight game and sixth overall this season with a right calf injury, linebacker LaMarr Woodley (hamstring) and safety Ryan Clark (concussion) are probable. Woodley has dealt with a series of hamstring issues over the last year but believes he will be on the field.

“I’m not worried about it at all,” Woodley said. “The things that have happened this year, it just takes a little time for it to settle down and heal, and then I’ll be ready to play. I feel a lot better today, and I’ll be ready to play Sunday.”
