CHAPEL HILL, N.C. -- 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 against 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 consecutive 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 coach Larry Fedora, was not in attendance Monday.
Fedora customarily declines to discuss the health of his players and stuck to that policy Monday, saying that "if you want to talk about injuries with our people, I'm not going to talk about them, so you might as well not bring up the question."
InsideCarolina.com was the first to report the severity of Renner's injury.
