Vikings tight end Josh Oliver left Sunday’s win over the Buccaneers with an injury that could keep him off the field for a long time.

Ian Rapoport of NFL Media reports that Oliver is believed to have a torn biceps. He will have an MRI on Monday to confirm that diagnosis and would be out indefinitely if the testing shows a tear.

Oliver played more than half the team’s offensive snaps during their 3-0 start to the season. He had three catches for 46 yards in the first two games, but did not have any catches in Tampa.

T.J. Hockenson is the lead tight end for the Vikings. Gavin Bartholomew is the only other tight end on the 53-man roster.
