Update: 1:12 p.m.:

The report from the Redskins is that Jammal Brown suffered a right groin injury. He suffered the same injury in the game against San Francisco in Week 9, then missed the following game against Miami.

Original post:

The Washington Redskins will be without starting right tackle Jammal Brown as they take on the New England Patriots. The veteran suffered a leg injury during pre-game warmups at FedEx Field.

Brown had been hampered occasionally over the last several weeks by a sore right hip, the same hip on which he had surgery in 2009 to repair a torn labrum. But it wasn’t clear whether Brown suffered an injury there.

The Redskins already are without starting left tackle Trent Williams, who is suspended for the rest of the season for violating the league’s substance abuse policy. Veteran Sean Locklear competed with rookie Willie Smith in practice this week for the starting left tackle duties and appears to have won. He took all of the left tackle snaps during pre-game warmups.

Tyler Polumbus, who spent the week working as a backup left guard and backup right tackle, took all of the snaps at right tackle when Brown was hurt and appears set to start there.

This will mark the seventh different offensive line combination that the Redskins have used this season.
