What is the WEC?
The WEC was a US-based MMA promotion started in 2001 by Scott Adams and Reed Harris. For its first five years, it operated independently, running most of its cards at the Tachi Palace Hotel & Casino in Lemoore, California, and airing on HDNet. In December 2006, Zuffa, the company that also owned the UFC, bought the WEC and ran it as a separate sister promotion with its own roster and champions.
What set the WEC apart was its attention to smaller fighters. While the UFC of that era topped out its interest at lightweight and above, the WEC leaned into bantamweight and featherweight, divisions the UFC did not yet have. That focus turned the promotion into the proving ground for a generation of lighter-weight talent, and it is the main reason fans still bring the name up today. When the UFC finally added those divisions, it did so by absorbing the WEC.
How the WEC worked
The most recognisable thing about the WEC was its cage. Under Zuffa, the promotion adopted a smaller version of the UFC’s octagon, 25 feet across instead of the standard 30, and its blue canvas earned it the nickname “the little blue cage.” Before the Zuffa purchase, the WEC fought inside a five-sided pentagonal cage.
The rules matched the UFC’s, so the fights themselves looked familiar to any MMA fan. The difference was the size of the athletes and, by extension, the pace. In its final years, the promotion ran three weight classes: lightweight (155 lb), featherweight (145 lb), and bantamweight (135 lb).
WEC events aired on HDNet and later moved to Versus, where they averaged around 575,000 viewers per card according to figures compiled by Wikipedia. The promotion held exactly one pay-per-view event, WEC 48 in April 2010, headlined by featherweight champion José Aldo defending his belt against Urijah Faber.
WEC vs UFC
Because the two promotions shared an owner and a rulebook, casual fans often assumed the WEC was simply a smaller UFC, or that the two competed against each other. Neither is quite right. The WEC was a sister promotion under Zuffa, deliberately positioned to develop the lighter divisions rather than to rival the UFC for the same fighters.
| Feature | WEC | UFC (same era) |
| Owner | Zuffa (from Dec 2006) | Zuffa |
| Cage size | 25-foot octagon | 30-foot octagon |
| Weight-class focus | Lightweight and below | Lightweight and above |
| Primary US broadcaster | Versus | Spike |
| Status | Folded into the UFC in 2011 | Ongoing |
The clearest way to think about it: the WEC handled the weight classes the UFC had not built yet, and once the UFC wanted them, the WEC’s job was essentially done.
What happened to the WEC
On October 28, 2010, UFC president Dana White announced that the WEC would merge into the UFC. The two had been run separately since the 2006 purchase, and speculation about combining them had circulated for years, partly because of overlapping lightweight rosters and competing television deals.
The final WEC card, WEC 53, took place on December 16, 2010, in Glendale, Arizona. It carried two title fights: Benson Henderson against Anthony Pettis for the lightweight belt, and Dominick Cruz against Scott Jorgensen for the bantamweight belt. Pettis won a decision after landing the off-the-cage strike that became known as the “Showtime Kick,” one of the most replayed moments in MMA history.
The merger completed in early 2011. The UFC added the featherweight and bantamweight divisions to its own lineup starting at UFC 125 on January 1, 2011. José Aldo carried his WEC featherweight title over to become the inaugural UFC featherweight champion, and Dominick Cruz did the same at bantamweight. Some of the shift had happened gradually: the WEC dropped its heavyweight and super heavyweight divisions after the 2006 sale, and its light heavyweight, middleweight, and welterweight classes were absorbed into the UFC between 2008 and 2009.
Notable fighters who came from the WEC
The WEC’s reputation rests largely on the fighters it developed. Urijah Faber was its biggest draw during the featherweight years, pulling in an average of 840,000 viewers when he headlined and topping a million twice, at WEC 34 and WEC 41. José Aldo, Dominick Cruz, Benson Henderson, and Anthony Pettis all built their names inside the little blue cage before winning UFC gold.
The list runs deeper than the champions. Donald “Cowboy” Cerrone, Joseph Benavidez, Chad Mendes, Carlos Condit, Dustin Poirier, Renan Barão, and future flyweight great Demetrious Johnson all fought under the WEC banner. Brian Stann held the WEC light heavyweight title before the division moved to the UFC. By UFC.com’s count, more than 15 fighters from just the final three WEC weight classes went on to hold or challenge for UFC titles.
Frequently Asked Questions
When did the WEC start and end?
The WEC was founded in 2001 and held its final event, WEC 53, on December 16, 2010. Its divisions were fully absorbed into the UFC in early 2011.
Why did the WEC focus on lighter weight classes?
After Zuffa bought the WEC in 2006, it positioned the promotion around bantamweight and featherweight, divisions the UFC did not run at the time. This kept the two promotions distinct and developed talent the UFC could later absorb.
What was the WEC’s smaller cage?
The WEC used a 25-foot octagon, five feet narrower than the UFC’s 30-foot cage. Its blue mat gave rise to the nickname “the little blue cage.”
Did WEC champions keep their titles in the UFC?
Two did directly. José Aldo became the first UFC featherweight champion and Dominick Cruz the first UFC bantamweight champion, both carrying their WEC belts into the newly created divisions.
Who was the WEC’s biggest star?
Urijah Faber. His featherweight run made him the promotion’s top ratings draw and one of the faces most associated with the WEC era.
