LUBBOCK, Texas (AP) -- The Big 12 says it will issue Texas Tech coach Tommy Tuberville a public reprimand for his sideline outburst at a graduate assistant during last weekend's double overtime win against Kansas.

Conference spokesman Bob Burda said Wednesday that Commissioner Bob Bowlsby issued the reprimand verbally. A letter also will be sent to the school, Burda said.

Tuberville said he has apologized to Kevin Oliver, whose headset and cap were knocked off when the coach pulled on Oliver's headset.

Video of the confrontation went viral on the Internet during Saturday's game after the Red Raiders had difficulty getting the right personnel on the field in their 41-34 win over Kansas in Lubbock.
