The four weight classes the WEC will promote are now flyweight, bantamweight (135), featherweight (145) and lightweight (155).
"With the addition of the flyweight division, the WEC has cemented its status as the home of the greatest lighter weight fighters in the world," WEC Vice President of Operations and Production Peter Dropick said. "We are excited to launch the 125 pound championship division, and look forward to giving our fans the best and most action-packed flyweight fights in the sport."
WEC welterweight champion Carlos Condit will make his UFC debut against Martin Kampmann at UFC Fight Night 18 on April 1 in Nashville, Tennessee. Number one contender Brock Larson will return to the UFC also at UFC Fight Night 18 in a fight against Jesse Sanders.
