Brandon Davies was dismissed from BYU's basketball team after he admitted to having sexual relations in violation of the school's honor code, the Salt Lake Tribune reported Wednesday.
BYU's honor code forbids students from having premarital sex and instructs them to "live a chaste and virtuous life."
The newspaper reported that Davies met with school officials on Monday.
BYU officials would only confirm Wednesday that Davies wasn't involved in anything criminal that resulted in his dismissal from the team.
University spokeswoman Carri Jenkins said an honor code review is under way to determine if the BYU sophomore will be allowed to remain in school, as well as his status with the team next season.
BYU's honor code also requires students to be honest; abstain from alcoholic beverages, tobacco, tea, coffee and substance abuse; and attend church regularly.
The school announced the dismissal on Tuesday night after being made aware of the violation Monday -- the same day that BYU (27-2, 13-1 Mountain West) vaulted to No. 3 in the ESPN/USA Today and AP polls.
In their first game without Davies on Wednesday, the Cougars lost 82-64 to New Mexico. BYU guard Jimmer Fredette said after the game Davies had apologized to his teammates.
"He told us he was sorry and let us down," Fredette said. "We told him it's OK. Sometimes in life we make mistakes. We've got to play through it."
Davies had started 26 of 29 games and averaged 11.1 points and a team-leading 6.2 rebounds.
The sophomore was a key member of BYU's frontcourt and was instrumental in helping contain San Diego State's forwards in the Cougars' 80-67 victory over the Aztecs.
No one discussed details of what occurred with Davies after the game but BYU coach Dave Rose discussed the school's controversial honor code.
"Everybody who comes to BYU, every student if they're an athlete or not an athlete, they make a commitment when they come," Rose said of the school's honor code. "A lot of people try to judge if this is right or wrong, but it's a commitment they make. It's not about right or wrong. It's about commitment."
Davies was one of Fredette's favorite targets in the post, ran the floor well and gave the Cougars length and size inside.
