The Redskins have released safety Kareem Moore, the team announced on Tuesday.
Moore had opened the season on the team's physically unable to perform list, sidelining him for the first nine games.
He was slowed by a knee injury since the beginning of training camp. He did not play in any preseason games.
Moore started a career-high 11 games in 2010, posting 65 tackles, one interception and two fumble recoveries.
He suffered a knee injury in 2010 preseason and he was eventually placed on injured reserve late in the year due to lingering soreness in the knee.
The Redskins retain four safeties on the roster: starters Oshiomogho Atogwe and LaRon Landry and reserves Reed Doughty and DeJon Gomes. Cornerback Kevin Barnes can also play safety in a pinch.
Moore joined the Redskins as a 2008 sixth-round draft pick.
