The Washington Redskins officially ended the season of offensive tackle Jammal Brown by placing him on the equivalent of the injured reserve list, a person familiar with the move said late Tuesday.

The Redskins did not announce the move. The team was facing a deadline Tuesday to activate Brown to the 53-man roster or end his season. Coach Mike Shanahan said Monday that he knew what probably would happen but he wasn’t ready to announce it at that point.

Brown, originally penciled in as the Redskins’ starter at right tackle, didn’t play all season.

He aggravated a hip injury while running just before training camp and underwent surgery.

Brown was not available to comment.

The Redskins placed Brown on the physically unable to perform list, leaving open the possibility that he would be activated to the 53-man roster late in the season. Brown resumed practicing this month but continued to be plagued by hip problems. Technically, Tuesday’s move involved Brown remaining on the reserve-physically unable to perform list, but that had the same effect of him being put on the season-ending injured reserve list.

Tyler Polumbus has been the team’s starter at right tackle all season in place of Brown.
