The Cleveland Browns fear left tackle Joe Thomas will require season-ending surgery on what they suspect is a torn triceps, sources told Ian Rapoport of NFL Network.
The 10-time Pro Bowler will undergo an MRI on Monday to confirm the extent of his injury.
An 11-year NFL veteran, Thomas played 10,363 consecutive snaps before being escorted off the field by trainers on Sunday versus the Tennessee Titans. He hadn't missed an offensive down since entering the league in 2007, and his streak is believed to be the longest in NFL history.
The Browns fell to 0-7 with the 12-9 overtime loss to the Titans. They'll face the Minnesota Vikings in London next week.
