Washington Redskins running back Chris Thompson practiced in a limited capacity on Wednesday after spending the past 12 days on the sideline because of a low ankle sprain.

Thompson took part only in individual drills, but still looked “a little tentative,” coach Jay Gruden said.

No determination has been made on the second-year back’s availability for Saturday’s game at Baltimore. Thompson has significant ground to make up as he aims to compete for a roster spot behind starter Alfred Morris and top backup Roy Helu Jr. Thompson’s competitors include fourth-year veteran Evan Royster and rookies Silas Redd and Lache Seastrunk.

Starting nose tackle Barry Cofield did not practice Wednesday because of soreness in his groin. But Gruden said that he believes Cofield will make a relatively quick return to action.

Backup inside linebacker Darryl Sharpton missed another practice with a high ankle sprain. Sharpton has practiced just once since injuring his ankle on Aug. 9.

Cornerback Tracy Porter was held out of team drills as he nurses a hamstring injury that he suffered in Monday night’s game.
