World Extreme Cagefighting

World Extreme Cagefighting (WEC) was an American mixed martial arts (MMA) promotion. It was purchased by Zuffa, LLC, the parent company of Ultimate Fighting Championship (UFC), in 2006. In its final incarnation, it was made up of 3 weight classes: 135, 145 and 155 lbs. To accommodate the smaller fighters, the WEC’s cage was 25 ft. in diameter—5 ft. smaller than the standard UFC cage.
