The Build-Up
The USA vs. Canada concept was a marketing exercise built around TKO Major League MMA fighters — five of the seven Canadian fighters were TKO champions. The card carried a meaningful narrative for Georges St-Pierre: a high-stakes test against B.J. Penn with a welterweight title shot on the line.
Rich Franklin's title defence against David Loiseau was a five-round fight between the division's dominant champion and a hard-hitting Quebec striker with a genuine fan following in Canada. The Lightweight division's return added historical significance to the card beyond the main event.
Main Event
Rich Franklin (c) vs. David Loiseau — UFC Middleweight Championship (5 rounds)
Rich Franklin controlled the five-round fight from start to finish. His striking accuracy and movement advantage over Loiseau were clear through every round. The scores of 50-42 on two cards reflected a one-sided championship bout. Franklin's second Middleweight title defence was decisive.
Rich Franklin retained the title and remained the division's most dominant fighter heading into the second half of 2006. His reign ended at UFC 64 in October 2006, when Anderson Silva finished him in round one.
Co-Main Event
Georges St-Pierre vs. B.J. Penn — Welterweight
Georges St-Pierre had won three straight since his only loss, to Matt Hughes. B.J. Penn had famously submitted Hughes for the WW title at UFC 46 in 2004 and was one of the most dangerous opponents in the division. The fight was close; GSP won by split decision 29-28, 28-29, 29-28.
The win confirmed Georges St-Pierre as the top welterweight contender. He won the WW Championship at UFC 65 in November 2006, beginning a dominant reign that lasted until 2013.
