UFC has issued the following press release, which you can read in full at UFC.com:
"Toronto, Ontario, Canada – The Ultimate Fighting Championship® announced today that tickets for UFC® 129: ST-PIERRE vs. SHIELDS at Rogers Centre in Toronto on April 30 sold out minutes after being made available to the public. Rogers Centre was originally configured for 42,000 seats, but due to overwhelming demand, UFC and Rogers Centre officials reconfigured the venue to accommodate 55,000.
UFC® 129: ST-PIERRE vs. SHIELDS, which is presented by TapouT®, is the first major mixed martial arts event to ever be held in Ontario. The event doubles the largest gate and attendance records in UFC history. The previous gate record for a UFC event was $5.4 million, which was set on Saturday, Dec. 30, 2006 at MGM Grand Garden Arena in Las Vegas for UFC 66: LIDDELL vs. ORTIZ 2. UFC 124: ST-PIERRE vs. KOSCHECK 2, held at the Bell Centre in Montreal on Dec. 11, 2010, previously held the attendance record with over 23,000 fans.
With two UFC records already shattered, UFC 129 is also the largest single-day event gate in the history of Rogers Centre, which has played home to some of the world’s top entertainment and sporting events.
“UFC continues to set new milestones,” UFC President Dana White said. “We’ve sold 55,000 tickets in our first stadium event in Toronto and we continue to take the UFC to the next level.”
