The 11-year NFL veteran will have surgery within the next few days and then be placed on injured reserve, McDonald reports.
Oakland’s head coach Jack Del Rio told reporters on Wednesday that Tuck’s MRI results were “not good.” The NFL Network’s Ian Rapoport reported that the Raiders feared Tuck’s injury was a torn pectoral muscle.
Tuck sustained the shoulder injury in the fourth quarter of Oakland’s 16–10 loss to the Denver Broncos on Sunday. In five games this season, Tuck has recorded one sack and seven tackles.
Mario Edwards Jr., who was a second-round pick in the 2015 draft, will likely see more playing time in Tuck’s absence.
Oakland (2–3) has a bye this week and next plays on Oct. 25 in San Diego.
