NC State guard Lorenzo Brown will have exploratory surgery on his right knee on Tuesday.
The procedure will try to pinpoint the source of the discomfort in his knee.
There is no timetable on his return. An update will be provided after Tuesday's procedure.
A third-team All-ACC selection last season, Brown, a 6-foot-5, 189-pound guard from Roswell, Georgia, averaged 12.7 points, 6.3 assists, and 4.5 rebounds in his first season as the Wolfpack's starting point guard. He finished second in the ACC in assists and his 1.8 steals per game led the ACC.
