The Tennessee Titans believe that left tackle Taylor Lewan tore his ACL in their 42-36 OT win Sunday over the Houston Texans, but he will have an MRI on Monday morning to confirm the diagnosis, a source told ESPN's Chris Mortensen.
Lewan was injured in the third quarter. He did not return after walking gingerly to the locker room.
Now in his seventh season, the 29-year-old Lewan has been selected to three Pro Bowls.
Lewan's injury was first reported by Fox Sports.
