Cardinals' Ed Stinson questionable after suffering groin injury

TEMPE, Ariz. -- Arizona defensive lineman Ed Stinson was added to the Cardinals’ injury report Friday after pulling his groin while running toward the end of Friday’s practice, coach Bruce Arians said.

“We’ll monitor it and see how it is,” Arians said.

Stinson said he doesn’t think it’s that serious. He was listed as questionable for Sunday’s game against St. Louis, but the rookie couldn’t set odds on him playing.

“Just try to keep getting treatment and hopefully I’ll feel better,” Stinson said.

Losing Stinson would be a blow to the defensive line’s rotation, Arians said, because Stinson is playing about 37 snaps per game.

Fellow rookie Kareem Martin may pick up Stinson’s snaps but Arians said nose tackle Alameda Ta’amu could enter the rotation and see significant snaps for the first time this season.

“He’s getting better,” Arians said. “He’s still not back to where he was athletically.”

Running back Stepfan Taylor (calf) and linebacker Desmond Bishop (hamstring) were ruled out for Sunday.

Linebacker Lorenzo Alexander (knee), linebacker Marcus Benard (illness), running back Andre Ellington (foot), linebacker Larry Foote (back) and tackle Bobby Massie (ankle/knee) were all listed as probable.
