PFL 9 determined the finals for men's lightweight and welterweight, two of its most skilled divisions. In the main event, Clay Collard fought former Ultimate Fighting Championship contender Shane Burgos. Burgos had gone 1-1 during the PFL regular season, losing to Olivier Aubin-Mercier but triumphing over Yamato Nishikawa, only making the postseason due to a late replacement. Collard, meanwhile, had defeated the same Nishikawa but also recorded a gorgeous early second-round knockout of last year's lightweight finalist Steven Ray. Early on, Burgos attempted to grapple but soon abandoned that for slugging it out toe-to-toe with Collard in an incredible back-and-forth war. However, Burgos found his opponent tougher than most men he faced in the UFC. Collard repeatedly beat Burgos to the punch and landed big blows, including a terrific left hook counter that put Burgos on his butt in Round 2. Burgos came back very strong in the final frame, scoring devastating leg kicks and crisp combinations upstairs alike in what was very possibly the best PFL fight of the year thus far. However, it wasn't enough, as Collard took the verdict 29-28 across the board.
In the co-main event, one of PFL's biggest stars, 2022 lightweight champion Olivier Aubin-Mercier, battled dangerous Brazilian striker Bruno Miranda. Miranda came in with an impressive seven-fight winning streak dating all the way back to 2017. Early on, he looked very strong, landing repeated leg kicks and a big body punch, likely winning the opening frame. However, Aubin-Mercier wasn't discouraged, dropping Miranda with a left hand early in the second stanza, and slowly, methodically advancing position before dispatching him with brutal ground-and-pound at 4:41 of the second round.
In one welterweight semifinal, defending champion Sadibou Sy met Carlos Leal Miranda for a second time. Like their first meeting in 2022, it was a grinding, competitive affair, with numerous clinches and even an unfortunate low blow. Sy had an advantage in the striking, but Miranda found occasional success in the grappling, including a takedown in Round 2 that likely won him the stanza. However, Sy still won a split decision with two scores of 29-28 in his favor, continuing a seven-fight winning streak. Oddly, while Miranda should have lost a point due to missing weight by a pound, that didn't factor into any of the scores.
In the other 170-pound semifinal, former 2018 PFL welterweight champion Magomed Magomedkerimov, the last man to defeat Sy, entered as a huge favorite against Solomon Renfro. Renfro offered spirited resistance, defending many takedowns and limiting damage when his back was on the canvas. He arguably won the last round, but Magomedkerimov still took the clear unanimous decision.
With the two finals set, let's look at both in greater detail.
