The Washington Redskins have placed cornerback Phillip Buchanon on the season-ending injured reserve list, and have promoted rookie corner Brandyn Thompson back to the 53-man roster.

Buchanon, who re-signed with Washington for a second season this past summer, missed the first four games of the year while suspended for violating the league’s substance abuse policy.

Buchanon appeared in one game but missed the last game while nursing neck and knee injuries.

Last season Buchanon started five games and on the year recorded 49 tackles and two interceptions.

Thompson has appeared in two games for Washington. Drafted in the seventh round out of Boise State, he opened the season on the 53-man roster, then was waived and re-signed to the practice squad when Buchanon returned to action. Thompson was brought up to the official roster for last week’s game, and then re-signed to the practice squad on Tuesday.
