North Carolina, which self-reported that 13 football players committed secondary NCAA violations by reselling shoes given to them as part of the school's apparel deal, has contacted at least three other schools who it learned may have had players sell shoes to the same retailer.
A source told ESPN that the retailer told UNC it had bought shoes from other schools, including Michigan, Marquette and California. Officials from all three schools acknowledged, through athletic department spokesmen, that they were contacted by North Carolina and are in the process of investigating the claims.
On Monday, North Carolina suspended players found to have participated in the sale of shoes for between two and four games.
