The coach, Darius Cobb, said Rodney Blackstock, CEO of Hooplife Academy, paid him a total of $10,000 and sent he and McLemore's cousin to meetings with agents and others hoping to represent McLemore.
The cousin, Richard Boyd, denied going, but Cobb provided photos of the two on trips, according to the report.
These incentives could have affected McLemore's amateur status. Kansas said it is reviewing the case.
McLemore, a Wooden Award finalist, declared for the draft on April 9. McLemore is No. 2 on ESPN Insider Chad Ford's Top 30 Big Board.
