(CBS SPORTS) - While the world seems to be investigating the personal life of Texas A&M quarterback Johnny Manziel, it's being reported that the NCAA is investigating the Heisman Trophy winner for an entirely different reason.
According to a report from ESPN, the NCAA is looking into whether or not Manziel received compensation signed photos and memorabilia.
ESPN's Outside the Lines reports that, according to two sources, Manziel agreed to a five-figure fee to sign hundreds of pieces of memorabilia while in Miami for the BCS National Championship Game in January.
Three sources said Manziel signed photographs, footballs, mini football helmets and other items at the request of an autograph broker named Drew Tieman. Two sources, who are aware of the signing arrangement, told "Outside the Lines" that Tieman approached Manziel on Jan. 6 when he landed at the Fort Lauderdale-Hollywood International Airport to attend the game between Alabama and Notre Dame the next day.
After that meeting, three sources said, Manziel, accompanied by his friend and personal assistant Nathan Fitch, visited Tieman's residence and signed hundreds of items in the main room of the apartment despite the fact that there were many people in the room. Before Manziel left South Florida, after taking in the title game, he signed hundreds of autographs more, one source said.
The report goes on to say that NCAA assistant director of enforcement, James Garland, contacted Tieman in June to talk about Manziel-signed items that had shown up on eBay.
Neither the NCAA or Texas A&M would comment on the reported investigation.
If the NCAA were to rule that Manziel accepted money in exchange for the signed memorabilia he would be ruled ineligible.
