An NCAA investigation of Shabazz Muhammad will not be completed in time for the UCLA freshman to travel with the team for a series of exhibition games in China next week.
The university confirmed Wednesday that he will remain behind.
The 6-foot-6 swingman is the jewel of UCLA's highly touted freshman class.
The NCAA is trying to determine whether Muhammad received improper benefits from the brother of an assistant coach at his high school or from a financial planner who helped fund a summer team on which he played.
Scrutiny of top-level athletes has been a hot topic in the years since the NCAA found that USC tailback Reggie Bush and his family received cash and gifts from two would-be sports marketers in San Diego.
"The real issue here is, if you have high-profile players, your enforcement staff has to monitor those students at a higher level," the late Paul Dee, former chairman of the NCAA's Committee on Infractions, said at the time. "High-profile players demand high-profile compliance."
