Saturday night was a historic one for the UFC in Mexico City. It was just the second time the promotion has put on a show there, and the atmosphere was great for the sport. The altitude wasn't exactly ideal for all of the fighters at UFC 188, though.
Per Fox Sports UFC on Twitter, UFC head man Dana White said that a number of the fighters felt the effects of fighting 7,000-plus feet above sea level:
Dana White: This altitude kills you, here. Six guys puked in the back #UFC188

Only the strong were able to come out victorious under the conditions.
