FRISCO, Texas (AP) — The Dallas Cowboys have claimed safety Ibraheim Campbell and center Adam Redmond off waivers to address two positions that need depth because of injuries.

Dallas also signed defensive end Charles Tapper to the practice squad Sunday, a day after waiving the fourth-round draft pick from 2016.

Campbell, a fourth-year player, was in training camp with Houston before getting waived. The second-year pro Redmond was with Buffalo.
