The status of N.C. State wide receiver Jarvis Williams and North Carolina linebacker Kevin Reddick for next week is uncertain.
Williams and Reddick were ejected after a scrum at the back of the end zone after Owen Spencer's nearly miraculous touchdown catch for N.C. State in the third quarter.
ACC associate commissioner Mike Finn said the referee, Brad Allen, will file a report after the game. If Allen rules that either player was fighting, a suspension for the next game is possible.
If Allen cites the players for flagrant fouls, they won't be suspended. Finn expects a decision today.
Senior place-kicker Josh Czajkowski returned from a hamstring injury suffered two weeks earlier at Clemson to play a big role for N.C. State.
Czajkowski made both of his field goal attempts - from 47 and 24 yards - and three extra points. He made a quick recovery after initially being ruled out for the season and agreed with coach Tom O'Brien that he's kicking better now than before he was hurt.
Czajkowski said he's not trying to "overkick" anymore.
"I'm just trying to be smooth through the ball," Czajkowski said.
N.C. State senior wide receiver Darrell Davis returned to the field to catch three passes for 11 yards, including a 2-yard catch for the Wolfpack's first touchdown.
He had missed the previous two games in what O'Brien termed a "coach's decision." In August, he entered a deferred prosecution agreement on misdemeanor charges of possession of marijuana and drug paraphernalia in Wake County.
"I'm just happy to be back on the field with my team," Davis said. "It hurt me that I hurt them because I wasn't out there on the field."
The loudest cheer on North Carolina's senior day was for tight end Zack Pianalto, who limped onto the field without his crutches.
Pianalto played in six games this season before suffering a season-ending leg injury, catching 30 passes for 311 yards.
The award for originality goes to an N.C. State fan who brought a life-sized cardboard cutout of O'Brien into a parking garage for the game.
The fan attached a sign that said, "I own Butch."
After O'Brien improved to 4-0 against North Carolina coach Butch Davis, that fan must have left the stadium happy.
