The University of Notre Dame is warning fans that it has received reports and evidence of counterfeit tickets being sold for the season-opening football game against Texas on Sept. 5.
Associate athletics director Rob Kelly said counterfeit tickets aren't unusual, but the number of reports the school is receiving and how far before the game they are being reported is unusual.
The university recommends that people who suspect they have counterfeit tickets should contact their local police.
The investigating law enforcement agency then can contact the Notre Dame Counterfeit Ticket Task Force.
The university said clues to counterfeit tickets include fuzzy printing, rough cuts or perforations, mismatched fonts or the absence of a three-dimensional shamrock hologram with Fighting Irish leprechauns.
