A trilogy is defined as a series of three novels, movies, etc. that are closely related and involve the same characters or themes.
On Saturday, UFC heavyweight champion Cain Velasquez completes his series of three bouts with Junior dos Santos in Houston. The third battle sold out in less than three days and could set the Toyota Center record for highest-grossing event, already held by the UFC.
The event also will mark the 10th trilogy completed solely inside the UFC Octagon. Depending on how the fight goes, it could take its place among some other notable UFC trilogies.
Randy Couture versus Chuck Liddell (UFC 43, UFC 52, UFC 57)
Randy Couture already had won two UFC heavyweight titles when he stepped down in weight to challenge Chuck Liddell for the interim light heavyweight title at UFC 43 in June 2003. Liddell was 11-1 and coming off a brutal head-kick knockout of Renato Sobral. Couture landed four of five takedowns and outstruck Liddell 46-22 in significant strikes to win the title by third-round TKO. The two men met again in April 2005 at UFC 52 after both served as coaches on the debut season of “The Ultimate Fighter.” Liddell won the rematch, knocking out Couture 2:06 into the first round to win the undisputed light heavyweight title. Their third matchup took place at UFC 57 in February 2006 with Liddell still champion at 205 pounds. Liddell controlled the fight, landing 18 head strikes, including the final blows to a downed Couture to win by TKO in the second round and retain the title. Both men were eventually inducted into the UFC Hall of Fame (Couture in 2006, Liddell in 2009).
Georges St-Pierre versus Matt Hughes (UFC 50, UFC 65, UFC 79)
Another Hall of Famer, Matt Hughes, was involved in two trilogies inside the UFC Octagon. Hughes landed on the losing end of both at 1-2, and while his trilogy with BJ Penn was memorable, it’s his rivalry with Georges St-Pierre for the UFC welterweight title that is remembered. At UFC 50 in October 2004, former champion Hughes faced a young 24-year-old from Canada in St-Pierre for the welterweight title. With 1:14 left in the first round, Hughes gained his second takedown of the fight and eventually secured an arm bar on St-Pierre, forcing a tapout with one second remaining to become a two-time UFC welterweight champion. Hughes made two defenses of the title before meeting St-Pierre again at UFC 65 in November 2006. St-Pierre outstruck the champion 45-10 and landed a devastating head kick and punches to win the title by TKO in the second round. December 2007 was the final battle at UFC 79. Hughes and GSP once again fought for a vacant interim title, as undisputed champion Matt Serra was out because of injury. St-Pierre landed three takedowns and finished Hughes via arm bar in the second round. That fight remains St-Pierre’s second UFC victory by submission in 20 fights. Hughes was inducted into the UFC Hall of Fame in 2010, before finishing his second trilogy with Penn and retiring in 2011.
Frankie Edgar versus Gray Maynard (Ultimate Fight Night 13, UFC 125, UFC 136)
At UFC Fight Night 13 in 2008, two undefeated lightweight prospects took to the Octagon in Frankie Edgar (9-0) and Gray Maynard (4-0, 1 NC). Maynard used his Michigan State wrestling background to score nine takedowns on "The Answer," winning 30-27 on all scorecards. Fast-forward to New Year’s Day 2011 and Edgar was the reigning and defending UFC lightweight champion. Maynard was still undefeated and the No. 1 contender to Edgar’s title when they fought at UFC 125. Edgar was knocked down three times in the first round and on the verge of losing to Maynard again, this time for the title. But the New Jersey product fought back valiantly, outstriking Maynard 85-46 for the remaining four rounds to earn a split decision draw. The third fight was inevitable and took place at UFC 136 seven months later. Maynard was again the aggressor, outstriking Edgar 24-11 in the first round and earning another knockdown against the champ. As with the second fight, Maynard slowed and Edgar battled back. In the fourth round, Edgar landed 21 significant strikes to 5 for Maynard and finished "The Bully" with punches to the head. The fight was stopped at 3:54 of the round with Edgar winning by TKO and retaining his UFC lightweight title. Edgar moved to featherweight in February 2013 and Maynard will face Nate Diaz at "The Ultimate Fighter 18" finale in November of this year. While it is their third fight, the first on the "The Ultimate Fighter" is not considered an official bout.
Ken Shamrock versus Tito Ortiz (UFC 40, UFC 61, “UFC Fight Night: The Final Chapter”)
Vendetta. Bitter Rivals. The Final Chapter. Those were the titles of the trilogy fights between Ken Shamrock and Tito Ortiz and did they ever fit the descriptions. After 1999 victories over Lion’s Den fighters Jerry Bohlander and Guy Mezger, Ortiz berated the Shamrock camp with taunts and T-shirts, enraging the "World’s Most Dangerous Man." Shamrock also was in the middle of a pro wrestling career, but made his Octagon return at UFC 40 in November 2002 to challenge Ortiz for the UFC light heavyweight title. In what was arguably one of the pivotal moments in UFC history, Ortiz dominated the former UFC Superfight champion in significant strikes 74-12, and takedowns 3-0. The fight was stopped in the third round by Shamrock’s corner, and Ortiz retained his title. Shamrock would be inducted into the UFC Hall of Fame the following year, but his career was not over. The two crossed paths again in 2006, not as opponents in the cage, but rather coaches on Season 3 of "The Ultimate Fighter." Verbal spats arose and the two men again faced off at UFC 61 in July 2006. Shamrock started strong, but Ortiz secured a takedown and landed elbows in the guard. Referee Herb Dean controversially stopped the fight at the 1:18 mark, giving Ortiz his second victory over Shamrock. The third fight was in October 2006 at UFC Fight Night: The Final Chapter. Ortiz landed a takedown 40 seconds into the fight and finished Shamrock with strikes 2:23 into the fight. Ortiz would be involved in one more trilogy during his UFC career, losing the final two bouts of his trilogy with Forrest Griffin. The third fight ended his UFC career on the same weekend he became the eighth fighter inducted into the UFC Hall of Fame.
Velasquez and dos Santos will fight for the third time this Saturday to finish the 11th trilogy in UFC history. Will this be the last? Unlikely. Here are some potential UFC trilogies for each division you may see in the coming years.
Heavyweight: Frank Mir versus Antonio Rodrigo Nogueira (2 fights): Mir needs to beat Alistair Overeem or he might face a release after fighting in the UFC since 2001. Nogueira is at the tail end of his career and Mir was the first man to make "Big Nog" submit in his MMA career.
Light heavyweight: Lyoto Machida versus Mauricio Rua (2 fights): This would require one fighter to move weight classes, most likely Machida back to 205. They split the first two over the title and a third battle could certainly go either way.
Middleweight: Anderson Silva versus Chris Weidman (1 fight, 1 upcoming): If Weidman wins at UFC 168, there won’t be a third fight. But if "The Spider" is victorious, you’d have to think either Weidman gets an immediate rematch or can work his way back to the title before Silva's contract runs out.
Welterweight: Carlos Condit versus Martin Kampmann (2 fights): While Condit certainly looked sharp against "The Hitman" in earning a TKO victory, Kampmann will always be lurking in the welterweight picture. He’d have to pull off two or three wins in a row somewhere along the line if he's to face "The Natural Born Killer" again.
Lightweight: Nate Diaz versus Gray Maynard (1 fight, 1 upcoming): Matt Wiman and Mac Danzig have fought twice, but Wiman won both, which essentially puts that out. Technically this will be the third fight of Diaz versus Maynard (they fought on TUF 5), but officially two on their fight records. Still, a Diaz win at the TUF 18 finale could make a third official fight very interesting.
Featherweight: Cub Swanson versus Dustin Poirier (1 fight): The odds gets a little longer starting at 145 because of the recent UFC addition, but these two should be in the division for a while. Swanson is currently ranked sixth and defeated eighth-ranked Poirier by unanimous decision in February.
Bantamweight: Michael McDonald versus Sergio Pettis (0 fights): With Jose Aldo probably moving to lightweight and Renan Barao to featherweight, bantamweight trilogies look bleak. Michael McDonald is 22 and Sergio Pettis is 20 ,so with success, they’ll be around a while. The question is if the younger Pettis’ future is at 135 pounds or 125.
Flyweight: Demetrious Johnson versus Joseph Benavidez (1 fight, 1 upcoming): By year's end, these men will have fought twice. If Benavidez wins the rematch at the TUF 18 finale, expect these two to finish the rivalry in mid to late 2014.
Women’s bantamweight: Ronda Rousey versus Sara McMann (0 fights): Rousey-Tate would be the obvious choice because they will have fought twice by year's end, but Tate has to win at UFC 168. Many see McMann's wrestling as the key to beating Rousey. Whoever beats the No. 1-ranked women’s fighter certainly would have to face "Rowdy" Ronda again.
