Ryan Torain, Chris Horton leave hurt

DETROIT -- Washington Redskins running back Ryan Torain left Sunday's game against the Detroit Lions at halftime with a hamstring injury.

With Clinton Portis and Chad Simpson inactive, rookie Keiland Williams was left as Washington's only healthy running back. The team said Torain's return was questionable.

Redskins safety Chris Horton was ruled out of the game with a first-half ankle injury.
