Arizona officials said Friday their ongoing investigation has yet to find any evidence backing Arizona State star Torian Graham's claims that a Wildcats fan called him a racial slur before Thursday's game.
Before the Sun Devils' loss to the rival Wildcats in Tucson, Graham extended both middle fingers toward fans as he walked to the locker room. A video tweeted by Shane Dale of ABC 15 in Phoenix captured the incident.
After the game, Graham tweeted an apology but cited "racial slurs" as the catalysts for his actions. The tweet has since been deleted.
