EL PASO, Texas -- Players from Notre Dame and Miami will not be allowed to cross the border into one of Mexico's most dangerous cities during their free time before the Hyundai Sun Bowl.

Notre Dame coach Brian Kelly took his team's passports before the Fighting Irish 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. El Paso borders the Mexican city of Cuidad Juarez, which is wrapped in a drug war. Officials say more than 3,000 people have been killed there this year alone, and the vast majority of crimes in the city are never investigated.

The Sun Bowl is Friday.
