Currently riding a five fight win streak dating back to his World Extreme Cagefighting days, Ultimate Fighting Championship featherweight Dustin Poirier is probably one of the hottest 145-pounders in the promotion today.

The UFC is MMA . It is the number one mixed martial arts promotion in the entire world.

A self-admitted ‘very nervous person,’ the 29-year-old says he sometimes gets so worked up before a match he vomits.

It would prove a stiff challenge for Couture, now a UFC Hall of will watch another student, welterweight contender Mike Pierce, try to take one step closer to championship contention.

Nobody brings it quite like the heavyweights, whose combination of one-punch power and cumulative size make for highlight-reel endings more often than any other weight class.

It’s an inhospitable, limbo-like state where talented mixed martial arts fighters can find themselves after losing to reigning champions twice in one-sided bouts, yet are clearly among the top five in the division, and will probably be favored against almost anyone but the top dog.
