FILE - In this Oct. 17, 2009, file photo, Clemson coach Dabo Swinney, center, is restrained by assistant coach Danny Pearman as he yells at referee Jerry Magallanes during the first half of the team's NCAA college football game against Wake Forest in Clemson, S.C. Pearman said he made a “grave mistake” when he repeated a racial slur to ex-Tigers tight end D.J. Greenlee at practice three years ago. The incident came to light Tuesday, June 2, 2020, when former player Kanyon Tuttle posted about it on social media. Tuttle was responding to the school's post of Swinney's comments Monday about the death of George Floyd in Minneapolis last week. (AP Photo/Mary Ann Chastain, File)
