North Carolina says senior quarterback Bryn Renner will have season-ending shoulder surgery.
The team said on its official Twitter account Tuesday that the procedure on Renner's left, non-throwing shoulder is scheduled for Wednesday at UNC Hospitals.
The injury likely makes redshirt sophomore Marquise Williams the full-time starter. Williams and Renner have rotated during the past few weeks.
Renner separated his left shoulder during the Tar Heels' victory over North Carolina State on Saturday. He returned midway through the fourth quarter after team medical staff popped it back into place.
Renner is the Atlantic Coast Conference's third-leading passer, throwing for 252 yards per game, with 10 touchdowns and 1,765 yards passing.
He led North Carolina (3-5, 2-3) to two straight wins following a 1-5 start.
