Teams are hesitant to play running backs in the preseason too much, let alone try to make something happen on a play that doesn't count. Washington Redskins RB Clinton Portis partially dislocated his left shoulder on Wednesday in the team's opening series against the Cincinnati Bengals. An MRI that was taken showed that the bone popped out of the shoulder socket temporarily, and will require rest and exercising to recover.

Portis injured his shoulder after chasing down Bengals defensive back Keiwan Ratliff after he had intercepted QB Mark Brunell. Portis made the tackle, but instead of feeling good about his effort, it cost him. Last year, Portis started every game and ran for 1,516 yards. At the moment, Ladell Betts is Portis' primary backup. Last year, Betts carried the ball 89 times for 338 yards.

After the game, Portis stated that he felt the pain, and hoped that he could play in the preseason still. However, the Redskins are just hoping he'll be ready for Week 1 - when it counts.

PFC Analysis: In fantasy leagues, Portis still has a lot of value, don't panic yet. This type of injury could keep him out a week or two, but he's still worth drafting for all of the contributions he'll make this season.
