N.C. State has asked the ACC to review an altercation from Saturday's 13-0 win over North Carolina, Wolfpack coach Tom O'Brien said Monday.
O'Brien did not provide any details about the play, or the players involved, but said: "We have sent something to the conference office and they can be a judge."
Associate ACC commissioner Michael Kelly said the league has no comment. According to UNC spokesman Kevin Best: "We're not aware of any issue involving one of our players."
It's the third straight year some type of on-field altercation has occurred during or after the game between the two rivals.
UNC linebacker Kevin Reddick and State receiver Jarvis Williams were both ejected from the 2010 game in Chapel Hill after Reddick threw a punch at Williams after a third-quarter touchdown.
After the 2009 game in Raleigh, UNC defensive end Donte Paige-Moss took a swing at State linebacker Sterling Lucas as players from both teams met at midfield after the game. Moss was subsequently suspended for UNC's bowl game in Charlotte.
Earlier this season, UNC was involved in a league review of an incident with Miami defensive tackle Micanor Regis. Regis was suspended one game by Miami for punching UNC receiver Dwight Jones in the groin during the game in Chapel Hill on Oct. 15.
The ACC reviews the plays but does not administer the punishment.
O'Brien said the report of the incident from this year's game was a routine submission to the league office in Greensboro.
"It's like every week when we see things on tape," O'Brien said. "We would ask (ACC officials coordinator) Doug Rhoads to give us what his input to think if it was something that should have been called or something that the conference should be aware of."
