Now that we’ve met TUF 12‘s lightweight contestants, it’s time to start building some hype for the rival coaches. SPIKE has provided CagePotato.com with this exclusive promo for The Ultimate Fighter: Team GSP vs. Team Koscheck, in which St. Pierre and Kos face off during a pretty nasty-looking storm. Personally, we’d be huddled in a basement somewhere, but you know how these fighters are — you can’t tell them anything. TUF 12 premieres Wednesday, September 15th, at 10pm/9c, directly following UFC Fight Night: Marquardt vs. Palhares.
