BYU has announced that two athletes -- football player Harvey Unga and women's basketball player Keilani Moeaki -- have decided to leave because of a violation of the school's honor code.

Unga was BYU's all-time leading rusher with 3,455 yards in three years, rushing for over 1,000 in each of those three years. In 2009, he rushed for 1,087 yards and 11 touchdowns, and was the Mountain West's leading rusher. The 6-foot, 237-pound Unga was first team All-MWC this past season.

"I fully support Harvey and his decision regarding his personal situation," BYU football coach Bronco Mendenhall said. "The possibility of not having Harvey on the field in the fall would certainly have an impact on our team, but my main concern right now is in supporting Harvey."

According to the Las Vegas Sun , Unga will be attempting to enter the NFL supplemental draft held in July.
