On Wednesday night, PFL concludes the 2021 season with a loaded card featuring six championship bouts and the return of boxing great Claressa Shields for her second professional MMA bout. It's a huge night for the promotion that should bring plenty of action with $1 million on the line for the winner in each of the championship fights.

In the night's main event, Kayla Harrison will look to win the women's lightweight tournament -- and the $1 million prize -- for the second time in what could be the final fight of her PFL career. Harrison takes on Taylor Guardado in the tournament finals. Harrison is a two-time Olympic gold medalist who has been dominant since transitioning to mixed martial arts, picking up an 11-0 record with nine stoppage victories. Guardado entered the season 0-1 as a professional but has won three fights to reach the finals, where she will look to score a massive upset as a +1400 underdog.

The welterweight title fight serves as the co-main event as well as a much-anticipated rematch. Magomed Magomedkerimov faces off with Ray Cooper III in a battle of the last two winners of the 170-pound title. Magomedkerimov earned the first incarnation of the title in 2018 with a second-round submission of Cooper. Then, Cooper rebounded in 2019 to stop David Michaud in the second round and claim the title. Now, the two enter this showdown on massive win streaks (Magomedkerimov's last defeat coming all the way back in 2015).

Elsewhere on the card, Bruno Cappelozza challenges Ante Delija with the heavyweight title on the line. Movlid Khaybulaev and Chris Wade face off with the featherweight title at stake. Former UFC fighter Antonio Carlos Junior takes on Marthin Hamlet for the light heavyweight crown. And Loik Radzhabov battles Raush Manfio for the lightweight title.

While not a championship bout, Claressa Shields' fight on Wednesday night is likely to grab many of the headlines coming out of the event. Shields is the greatest female boxer in history, having won world titles in three weight classes. Looking for a new challenge, Shields signed with PFL where she battled Brittney Elkin, a fighter who entered the cage with a 3-6 record and still dominated much of the fight, taking advantage of Shields' lack of grappling skills before gassing out and allowing Shields to score a third-round TKO. Shields now faces 2-0 Abigail Montes, a fighter who likely has less grappling skills than Elkin presented in her fight with Shields.

Here's the fight card for PFL World Championship with the latest odds from Caesars Sportsbook.
