Washington’s newest running back, Tashard Choice, says his sore hamstring likely will keep him from playing Sunday against San Francisco, but he hopes to make his Redskins debut Nov. 13 at Miami.

The Redskins claimed Choice off waivers Monday. He was waived by the Dallas Cowboys two days earlier. The chance to play for a division rival, he says, is a blessing in disguise.

In a reserve role, Choice had only 75 yards on 28 carries in six games for Dallas this year. He had only four starts in less than four seasons there and said he didn’t have an opportunity to showcase himself with the Cowboys.

“Two or three carries a game, four carries a game, different spurts during a game -- it hurts your production,” Choice said. “The main thing now is, just once you get in a rhythm, keep rolling and make the most of opportunities. Protect the quarterback, don’t put the ball on the ground. You’re straight then.”

Choice injured his shoulder in an Oct. 23 game against St. Louis, and tweaked his hamstring later in the week. There were news reports that he might accept an injury settlement and sit out the remainder of the year, but Choice said that “never crossed my mind.”

“My thing was, Where would I land?” he said.

Choice said his hamstring is still “not 100 percent.” The Redskins entered last Sunday’s loss against Buffalo with only two tailbacks on the active roster — Ryan Torain and rookie Roy Helu — and could do the same this weekend against the 49ers.

Choice said he arrived in the Washington area Tuesday and spent the entire day at Redskins Park.

“Yesterday was a storm,” he said. “But today is calm. It’s going to get even better, day in, day out, getting to know my new teammates. I just can’t wait to play, man. I can’t wait to get on that field and play myself.”

If he is inactive Sunday, Choice essentially has an extra week of practices to learn the Redskins scheme and get comfortable with the Washington offense. He doesn’t think that will be a problem; he says he’s a fast learner.

“Protect the football is always the same. Just terminology. Once I get that, I should be fine,” he said. “So going over the playbook, doing some extra studying, getting with coach, I should be fine.”

“I’m rolling. I got a lot to prove. I’m excited. I’m glad Coach Shanahan gave me an opportunity to come out here. I’m excited about getting a chance to play. I’m just going to be rolling. I want to make plays for the offense, help the guys out.”
