The devastating altitude of Mexico City looks set to play a decisive factor when the Oakland Raiders play the Houston Texans on Monday night.
You can catch the International Series game at 1.15am, live on Sky Sports 1 HD.
The Azteca Stadium, a venue perhaps remembered by British fans as the scene at World Cup '86 of 'The Hand of God', will host the NFL's annual trip to Mexico.
But it sits 7,280 feet above sea level and, coupled with the smog-like pollution over the city, it is expected to cause carnage with both sets of players throughout Monday's game.
The Texans have won six out of nine games this season so sit top of the AFC South, while the Raiders are top of the AFC West with a 7-2 record.
