The Browns claimed guard and former seventh overall draft pick Jonathan Cooper off waivers from the New England Patriots on Monday.
The Arizona Cardinals picked Cooper in the first round in 2013 and traded him and a second-round selection to the Patriots in March for defensive end Chandler Jones.
Cooper, a 6-foot-2, 310-pound University of North Carolina product, had been practicing as the Patriots' starting right guard in the offseason until he suffered a foot injury during the third practice of training camp. With Shaq Mason taking control as their starting right guard, the Patriots waived Cooper on Saturday.
