The NCAA has warned each school recruiting top prospect Shabazz Muhammad that it is investigating financial dealings that could compromise Muhammad's amateur status.

According to sources, the NCAA is specifically investigating Muhammad's family and financial advisers Benjamin Lincoln and Ken Kavanagh. Sources indicated that Lincoln paid for at least two of Muhammad's unofficial visits to college campuses and that Kavanagh helped fund Muhammad's summer team, the Las Vegas-based Dream Vision Foundation.

Muhammad's father, Ron Holmes, admitted that Lincoln has paid for unofficial recruiting visits.

"By 2010, Shabazz was getting a lot of interest from high major colleges, including North Carolina and Duke," he said. "We had an opportunity to take unofficial visits to both schools in North Carolina. Benjamin offered to pay for our plane tickets and hotel room. When we went on the visits, we filled out the NCAA compliance forms and fully disclosed that our family friend, Benjamin Lincoln, had paid for the trips.

"When we were approached by the NCAA, we cooperated naturally," he continued. "We had told the truth from the beginning and had disclosed everything. It is frustrating that we have been honest and above board from the start and now there are those who are questioning what we did. ... I don't think we've done anything wrong."

Muhammad is considering Duke, Kentucky, UNLV, UCLA, Arizona, and Kansas.
