Alexander visiting the Redskins

Posted by ESPN.com's Matt Mosley

Former Seahawks running back Shaun Alexander will visit Redskins Park on Tuesday and will probably sign with Washington, according to ESPN.com's John Clayton and Mike Sando. The Redskins need an extra running because Ladell Betts suffered a knee injury against the Rams.

Alexander worked with Redskins head coach Jim Zorn and running backs coach Stump Mitchell when they were in Seattle. He had an excellent career in Seattle, but he was largely ineffective last season and was released by Mike Holmgren.

The main reason Alexander hasn't been able to find a job is because he's not a complementary-type back. He's not a third-down back because he rarely catches passes, and he's not considered a good blocker. If the Redskins sign him, he'll mainly be an insurance policy. Clinton Portis has been brilliant this season, but he might occasionally need a series off. Rock Cartwright is capable of eating up some carries, but he's also a valuable special teams player.

I wouldn't expect Alexander to have more than five carries in a game. He'll just be there in case Portis gets hurt.
