The Washington Redskins have officially ruled right tackle Jammal Brown out of Sunday’s game against the New York Giants, the second straight start Brown will miss because of a strained left groin.

“That groin is still quite sore,” said Redskins coach Mike Shanahan.

Fourth-year pro Tyler Polumbus will start in place of Brown for a second consecutive game.

Also ruled out for Sunday’s game is fullback Mike Sellers, who hyperextended his elbow in last week’s game.

Listed as probable on the Redskins’ Friday injury report are linebacker London Fletcher (ankle), punter Sav Rocca (ankle), defensive end Stephen Bowen (knee), free safety Reed Doughty (rib) and receiver Donte Stallworth (ankle).

The Giants have ruled out center David Bass (neck), tight end Travis Beckum (chest), linebacker Mark Herzlich (ankle), safety Derrick Martin (back) and defensive end Osi Umenyiora (ankle/knee).

Listed as questionable for Sunday’s game on the Giants’ injury report was defensive end Justin Tuck (toe).

The Giants list running back Ahmad Bradshaw (foot) as probable. Linebacker Spencer Paysinger (hamstring) and safety Kenny Phillips (knee) also are expected to play.
