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.
Team spokesman Kevin Best said in a statement later Tuesday that Renner has a detached labrum and a broken bone in the shoulder.
"We are disappointed to lose a senior leader and a great teammate like Bryn," coach Larry Fedora said in the statement. "He has meant so much to the Carolina program and I've enjoyed coaching him the last two seasons. He is one of the most prolific quarterbacks in school history and his contributions will be sorely missed."
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 this season.
He led North Carolina (3-5, 2-3) to two straight wins following a 1-5 start.
The Tar Heels host last-place Virginia (2-7, 0-5) on Saturday.
The injury ends the college career of one of the program's top passers. Renner threw 28 touchdown passes as a junior and 26 in 2011 - the highest two single-season totals in school history.
He ranks third in program history behind T.J. Yates and Darian Durant in four career stat categories: yards passing (8,221), touchdowns (64), completions (668) and attempts (1,005).
Renner, who usually attends North Carolina's weekly news conference with Fedora on Mondays, was not in attendance this week.
