The Buffalo Bills have signed defensive end Ra’Shon Harris to the practice squad. Harris joins the Bills after being released by Pittsburgh prior to the regular season. The 6-foot-5, 300-pound defensive end entered the NFL as a sixth-round draft choice of the Steelers last season. Harris spent time on the Carolina Panthers' practice squad last year, appearing in two games and recording two tackles. He rejoined the Steelers on Oct. 14 and was inactive for the rest of the season. Source: The National Football Post
