Green Bay Packers linebacker Clay Matthews will not play Sunday against the Detroit Lions, head coach Mike McCarthy announced Wednesday. The All-Pro player injured his hamstring in Green Bay's Week 9 win over Arizona. McCarthy announced after that game that Matthews would be unavailable for at least two weeks, and the Packers' bye in Week 10 was not enough to speed up his recovery.
Matthews is in his fourth season out of Southern California. Through nine games of the 2012 season, he has registered 31 tackles and leads the Packers with nine sacks. He has a history of hamstring injuries, and missed time in training camp in his first three professional seasons due to hamstring issues. This marks the first time Matthews has sustained such an injury during the regular season.
Green Bay will also be without tackle Bryan Bulaga, who went on injured reserve this week following a hip injury, and cornerback Charles Woodson. There is no word yet from the team who will start in Matthews' outside linebacker position against Detroit, though rookie Dezman Moses is listed behind Matthews on the team's depth chart.
