Edward Rife faces a possible sentence of up to 40 years in prison and a $2 million fine, according to documents detailing terms of the plea agreement.
During a federal drug investigation, authorities raided Rife's home and west side tattoo shop. Among the items seized were several pieces of Ohio State football memorabilia.
A subsequent probe revealed that several current Ohio State football players had traded the items to Rife in exchange for tattoos. Ohio State later suspended the players and coach Jim Tressel for the first five games of the 2011 season.
Tressel is being investigated by the NCAA over allegations that he knew about the players' rules violations but did not inform his superiors.
