Browns released OLB Quentin Groves and LB Larry Grant. Groves, 30 next month, recorded four tackles and two sacks across 53 defensive snaps last season before landing on injured reserve with an ankle injury in November. Second-year OLB Barkevious Mingo will serve as the No. 3 edge rusher behind Paul Kruger and Jabaal Sheard. Grant was just signed last month.
