The freshman punched Trenell Troutman during the second half of Clemson's 45-10 victory. Booth was ejected for unsportsmanlike conduct and will miss the opening half of the next game, against Boston College on Saturday, in accordance with NCAA rules.
Swinney said Tuesday that Booth has apologized to the team and handled things well since. Swinney added that he has not had problems before with Booth, who has "money in the bank with me.''
Swinney said Booth rode back to campus by bus with managers instead of flying home with his teammates.
Booth is from Dacula, Georgia, and was rated a five-star prospect by several recruiting services.
