Dallas defensive tackle Henry Melton will miss the playoffs because of a right knee injury sustained in the regular-season finale at Washington.
Melton, who missed most of last season in Chicago with a torn anterior cruciate ligament in his left knee, was placed on injured reserve Tuesday with a bruised right knee.
Dallas replaced Melton by signing linebacker James Anderson, a third-round pick by Carolina in 2006.
Anderson spent seven seasons with the Panthers and one in Chicago before playing in seven games with Tennessee this season.
