LaRon Landry out against Vikings

ASHBURN, Va. -- Washington Redskins safety LaRon Landry and running back Ryan Torain have been ruled out for Sunday's game against the Minnesota Vikings.

Coach Mike Shanahan said Thursday that Landry will miss his second consecutive game with a left Achilles tendon injury. Torain is missing his third game in a row with an ailing hamstring.

The Redskins officially placed running back Clinton Portis on injured reserve because of a torn muscle in his lower abdomen.

Portis returned from a groin injury Sunday against Tennessee, but lasted only five carries before getting hurt again. He will have surgery and require at least two months of rehabilitation, ending his season with a career-low 227 yards on 54 carries with two touchdowns.

The Redskins signed running back Andre Brown to the 53-man roster and signed offensive lineman Jacob Bender to the practice squad.

Shanahan rearranged the schedule Thursday, holding an early practice so players could get home and celebrate Thanksgiving.
