The main event featured the third and final encounter between
Tito Ortiz and Ken Shamrock. At
UFC 61, the two fighters met for a second time, with Ortiz reigning victorious via technical knockout. However, some critics contend that the fight was stopped too early by referee
Herb Dean. At the
UFC 62 weigh-ins, UFC President
Dana White announced the third Ortiz-Shamrock encounter. Tickets went on sale on Tuesday, August 29, 2006, and sold out in two days. The two-hour broadcast drew a 3.1 overall rating, with the main event of
Tito Ortiz and
Ken Shamrock fighting for a third time drawing a 4.3 rating. Quoting MMA Weekly's Ivan Trembow, "That breaks down to an amazing 5.7 million viewers for the Ortiz vs. Shamrock fight. This shatters the UFC's previous record for the number of people watching a UFC fight at any given time." The overall ratings record would not be matched until
UFC 75 on September 8, 2007. ==Results==
