Mexico City, Mexico - It took a long time, but the UFC is finally putting an event in Mexico, and the response has been overwhelming.

All 21,000 tickets for UFC 180, which will be held November 15th at the Mexico City Arena, sold out in just eight hours, UFC President Dana White told Yahoo Sports on Thursday. The main event of the show will be a heavyweight title fight between Cain Velasquez, the first Mexican heavyweight champion, and Brazilian Fabricio Werdrum.

The two fighters are also coaching against each other on the first season of "The Ultimate Fighter: Latin America" which, according to White, attracted over seven million viewers for it's first episode on Tele visa, Mexico's largest network.

"I've been saying it for years that Mexico was going to be huge, and you're seeing that now," White said. "That's a massive number to pull for the first episode, and this thing is going to be massive down there."

"The Ultimate Fighting Championship is heavily invested in Mexico and will stage multiple shows there a year," the UFC President said.

The UFC announced the main card for the show on Wednesday. In addition to Velasquez-Werdum, it includes Kelvin Gastelum against Jake Ellenberger; Diego Sanchez against Norman Parke; Ricardo Lamas versus Dennis Bermudez; and Erik Perez, a Mexican, against Marcus Brimage.
