The Professional Fighters League crowned six world champions on Monday at PFL 11: Championship inside Hulu Theater at Madison Square Garden in New York.

In addition to some hardware, the PFL, which was rebranded from the World Series of Fighting in 2017, handed out six $1 million checks. It was the final show of the promotion's inaugural year, which consisted of a regular season and a playoff.

In the night's main event, welterweight Magomed Magomedkerimov (23-6) upset one of the year's standouts in Ray Cooper III via second-round submission. The finish came at the 2:18 mark, when Magomedkerimov secured a tight guillotine during a scramble.

After nearly tapping to a rear-naked choke in the first round, Cooper succumbed to the guillotine. The finish snapped a four-fight win streak for Cooper.

"I feel very good," Magomedkerimov said. "Everything went well."
