Austin, Texas ? Sophomore forward P.J. Tucker, the leading scorer and rebounder for No. 15 Texas, is academically ineligible and will miss the rest of the season, the school announced Thursday.

Tucker, averaging 13.7 points and eight rebounds a game, will stay in school and be allowed to practice but is not eligible for competition.

Texas (14-3) plays at No. 18 Oklahoma (14-2) on Saturday.

“I’m really disappointed that I’m going to have to miss the remainder of the season,” Tucker said. “I feel like I’ve let a lot of people down, including myself. I’ll spend the spring and summer focusing on my academics so that I can return to the team next fall.”

A team spokesman also said starting freshman center LaMarcus Aldridge was still out indefinitely because of a hip injury. He missed Texas’ win over No. 5 Oklahoma State on Monday night.

University officials have refused to comment on details of Tucker’s academic problems, citing federal privacy laws that protect student records. Tucker acknowledged that he did not earn enough credit hours to stay eligible.

“I feel for P.J. right now,” Texas coach Rick Barnes said. “We hope he can learn a huge lesson from this and come back as a stronger and more mature person. There’s no question that his loss will affect our team.

“He feels responsible for it. A prized possession has been taken away from him,” Barnes said.

Tucker’s loss is a huge blow for the Longhorns. Tucker has been the Longhorns’ floor leader this season, bringing an innate toughness and desire to win to a squad infused with freshmen.
