The cartel and drug violence in Cuidad Juárez has sown fear into residents along the Mexican and U.S. border – an angst that has now spread to college athletics.
The coaches of those teams will not allow their players to cross the border into Cuidad Juárez.
Notre Dame coach Brian Kelly took his team's passports before they flew to El Paso as a precaution. The Hurricanes didn't bring passports, either, and met with both local law enforcement and the FBI on Sunday shortly after arriving in Texas to further underscore the potential dangers of crossing the border.
Fans from both schools have also been urged to be cautious.
Mexican law enforcement have said more than 3,000 people have been killed there this year alone, and tens of thousands have been murdered since the country's president, Felipe Calderón, attempted an all-out crackdown on the cartels in 2006.
