UFC 102: Couture vs. Nogueira was a mixed martial arts event held by the Ultimate Fighting Championship (UFC) on August 29, 2009 at the Rose Garden in Portland, Oregon. It featured former UFC Heavyweight and Light Heavyweight champion, Randy Couture, facing off against former PRIDE Heavyweight champion and former UFC Interim Heavyweight champion, Antônio Rodrigo Nogueira.

Randy Couture was originally offered a title defense against Antônio Rodrigo Nogueira at UFC 81, however turned the fight down after his resignation from the UFC in October 2007. While Couture and the UFC sorted out their legal issues, Nogueira defeated Tim Sylvia for the UFC Interim Heavyweight Championship becoming the first fighter to hold both PRIDE and UFC title belts. Nogueira was then set to coach against Frank Mir on the eighth season of The Ultimate Fighter with the two facing off for the Interim Championship after the season aired.

Eventually Couture and the UFC reconciled and it was announced that he would return to the Octagon to defend his title against Brock Lesnar at UFC 91. Neither Couture or Nogueira were successful in their defense efforts and then faced each other in what amounted to a "losers bracket" of the UFC's mini heavyweight tournament.

Born in Manchester, Connecticut on July 28, 1969, White grew up in Las Vegas, Nevada, Ware, Massachusetts and Levant, Maine. White is a passionate Boston Red Sox fan. During his youth, he bounced back and forth between Boston and Maine.

Nathan Joel Marquardt (born April 20, 1979) is an American mixed martial artist. He is a three-time Middleweight Pancrase Champion and former UFC middleweight title contender.

As a middleweight (he now fights at welterweight), Marquardt was ranked the #4 best middleweight in the world by Sherdog and the #3 middleweight fighter in the world by MMAWeekly. He runs the High Altitude Martial Arts Academy in Aurora, Colorado.

Marquardt began his professional mixed martial arts career in 1999, amassing victories in various promotions before entering the Bas Rutten Invitational 4 tournament, which was organized in such a manner that the tournament winner was to be offered a contract with the Ultimate Fighting Championship. Despite winning the tournament, Marquardt was offered no such contract. Instead, he signed with Japan's Pancrase organization, which had fostered such fighters as Ken Shamrock and Bas Rutten. In his first Pancrase fight, Marquardt lost via submission to Genki Sudo.

Invited back to Pancrase for a middleweight elimination tournament, Marquardt defeated Daiju Takase, Kiuma Kunioku, and Shonie Carter to become the first middleweight King of Pancrase. Marquardt defended this title twice before being defeated by Kunioku in December 2001. A final encounter between the two fighters in December 2002 saw Marquardt defeat Kunioku once again to recapture the King of Pancrase championship, which he held for nearly a year.^{[citation needed]}
