A Sports Illustrated investigation released on Monday night alleged that since 2002, at least 28 Ohio State football players traded or sold their memorabilia.
Sources told the magazine that players have been trading memorabilia, including items bearing former coach Jim Tressel's signature, since at least his second season at Ohio State.
Tressel resigned on Monday morning amid an NCAA investigation into the coach's conduct.
The magazine reported that Tressel violated NCAA bylaw 10.1, unethical conduct, three times. The first when he failed to act when he was tipped off in April 2010 about six of his players selling their memorabilia for tattoos. The second was when he signed his standard form of compliance that declared that he knew of no violations. The third violation was in December when he was not forthcoming with school officials about his knowledge in the investigation.
Robert Rose, who played defensive end for Tressel told Sports Illustrated that he traded and "at least 20" others on the team exchanged memorabilia for tattoos.
The investigation also uncovered allegations that Ohio State players traded memorabilia for marijuana.
A second tattoo shop. Dudley'z Tattoos & Body Piercing, was also mentioned in the article. The store that since closed its West Broad Street location was allegedly the site where a former artist said that he remembered tattooing at least 15 players.
Tressel is scheduled to appear in front of the NCAA on Aug. 12 to state his case.
