The Mohegan Sun Arena is a 10,000 seat multi-purpose arena in Uncasville, Connecticut located inside the Mohegan Sun casino resort. The arena facility features 30,000 square feet (2,800 m2) of configurable exhibition space and a 400-foot (120 m) clear span. It was built by the Perini Building Company, and opened in October 2001.
The multi-purpose facility has hosted a wide variety of events; including the American Kennel Club, WWE, concerts from major classical, country, jazz, metal, rap, rock, and pop acts, as well as sporting events such as PBR events, Bellator, NCAA games, PBA tournaments, early UFC bouts, and the World's Strongest Man Super Series Competition. The largest event on record to have been held at the arena was the inaugural Barrett-Jackson collector car auction in the Northeast in 2016, for which 90,000 tickets were sold to the multi-day event.
Major network and cable television broadcasting companies, including CBS, NBC, ABC, FOX, ESPN and CNN have all produced events through this arena.
The arena originally served as home of the Mohegan Wolves arena football team until it was sold and moved to Manchester, New Hampshire in 2004.
On July 19, 2001, Uncasville was awarded an AF2 expansion team. On December 12, 2001, Mohegan Sun and Dr. Eric Margenau, President/Chief Executive Officer of United Sports Ventures, announced that the new expansion AF2 franchise would be named the Mohegan Wolves. Margenau introduced Gary Porter, as the head coach for the team that would first take the field April 5, 2002 at the Mohegan Sun Arena against the Albany Conquest. Gary Porter, previously led the expansion Peoria Pirates to a 7-9 record in 2001.
The team name was selected through a "Name the Team" contest sponsored by WCTY, Mohegan Sun and X-Tra Mart. A Jewett City resident, came up with the winning name. The winner won four season tickets for the 2002 Mohegan Wolves season, dinner for four on the night of the team's first home game, and a team merchandise package.
On January 28, 2003 the arena was announced as the official home court for the Connecticut Sun. Prior to the fall of 2002, the NBA operating model precluded any WNBA team without an NBA "brother" counterpart. By the time the Connecticut Sun moved in, Val Ackerman was the WNBA president and Mark L. Brown was the chairman of the Mohegan Tribe. While the arena is attached to the Mohegan Sun casino, the facility does not accept any form of sports wagering or sports booking because sports betting is illegal in Connecticut.
On September 8, 2005, as a companion to the arena, the Mohegan Sun casino opened a Connecticut Sun merchandise store called "Winter Essentials." It was the first store in the United States that sold professional basketball goods on casino ground. However, the store was closed when the casino underwent renovations in 2008. Connecticut Sun merchandise can now be purchased in the Arena during games.
On April 21, 2002, the Mohegan Sun Arena hosted the 2002 National Lacrosse League All-Star Game. The North Division (Calgary Roughnecks, Montreal Express, Ottawa Rebel, Rochester Knighthawks, Toronto Rock, Vancouver Ravens) defeated the South (Albany Attack, Buffalo Bandits, Columbus Landsharks, New Jersey Storm, New York Saints, Philadelphia Wings, Washington Power) by a score of 14-10. Steve Toll, of the Toronto Rock, was named the MVP of the event.
On August 5, 2014, the National Lacrosse League announced that the Philadelphia Wings would move to the Mohegan Sun Arena and be re-branded as the New England Black Wolves for the 2015 season. In their home opener, the Black Wolves defeated the Buffalo Bandits 12-8 in front of 5,768.
