University of North Carolina officials reportedly contacted three other schools in the wake of committing NCAA violations in the form of 13 football players selling shoes given to them as part of UNC's apparel deal with Jordan Brand.
According to ESPN.com's Darren Rovell and Nick DePaula, North Carolina reportedly spoke with officials from Michigan, Marquette and California after it found that players from those schools may have sold shoes to the same retailer as the North Carolina football players.
The 13 UNC players were suspended Monday for between two and four games each for their role in the sales.
