Dabo Swinney said Thursday night that sophomore offensive tackle Isaiah Battle "played pretty good" before committing "a really stupid personal foul" that got him kicked out of the game.
The incident came following N.C. State's late-game 23-play, eight-minute scoring drive as Clemson was trying to run out the clock. Battle was involved in an altercation with Wolfpack defensive back Jarvis Byrd.
Video shows Battle and Byrd apparently exchanging words in close quarters, and Battle then throwing a right-handed uppercut that landed under the chin strap and knocked Byrd to the ground.
"We had a very poor personal foul," Swinney told ESPN as he left the field after the game. That's not Clemson. I'm disappointed in that."
Later, during his radio interview, Swinney said that Battle "had the really stupid personal foul at the end of the game, but before that he played pretty good.
"And Shaq (Anthony) came in there and gave us quality time, and so did Kalon (Davis)," he added. "We need that. Depth makes us better in every realm."
During his post-game press conference Swinney said: "Very disappointed in Isaiah Battle. That can't ever happen. Really, really disappointed. That's not Clemson. That's a lesson for every one of those guys in there, something we talked a lot about in the locker room...I will say this, he took ownership. He apologized immediately and he apologized to the team."
Swinney has not yet addressed Battle's situation further, but for now it's certain that the sophomore will sit out at least the first half of the Wake Forest game next Saturday, per NCAA rules.
