The Oakland Raiders host the Texans on Monday night in Mexico City. The altitude at Mexico City is 7,382 feet above sea level compared to Denver's 5,280. The Texans lost 27-9 at Denver in October.
The Texans don't anticipate any problems.
"I don't really know much you can do to plan for it," offensive tackle Duane Brown said. "You have to try to get accustomed to it as much as possible, and then just ignore it. I'm sure there'll be some oxygen (on the sideline), but other than that, you just have to play your game."
The Texans and Raiders are going to Mexico City on Sunday, the day before the game.
