Coach Butch Jones said Monday that Paulk was dismissed due to a "personal conduct" issue.
The News-Sentinel included some details of the alleged incident:
According to a release from the Knox County Sheriff’s Office, an 18-year-old woman told a Sheriff’s Office Family Crisis detective Sunday that Paulk, identified as her ex-boyfriend, struck her in the mouth with his fist at a party at Quarry Trail Apartments on Saturday. The report said the woman had cuts to her lips, but refused medical treatment. As of Monday, she has refused to prosecute or take out an order of protection.
Paulk was expected to redshirt this season after undergoing knee surgery last October.
The Alpharetta, Ga., native was rated the No. 12 all-purpose back in the class of 2014 by the recruiting website Rivals.com. He also received scholarship offers from Ole Miss, Wisconsin and North Carolina, among other schools.
