Mike Perry and Conor McGregor had a stare-down at the end of the BKFC 41 event.
Perry improved to 3-0 in BKFC after former UFC middleweight champion Luke Rockhold retired during the second round of their fight.
Rockhold signaled an injury to his mouth and removed his mouthpiece as referee Dan Miragliotta waved off the fight at 1:15 of round two.
McGregor was seated cage side and asked to enter by Perry, as the two had a face-off and McGregor shared some words with Perry and the audience.
BKFC 41 included two previous opponents of McGregor’s, as Eddie Alvarez won a narrow split decision against Chad Mendes in an exciting five-round affair that featured several knockdowns.
Alvarez was awarded the decision with scores of 47-46, 46-47, and 47-46. After the fight, Mendes announced his retirement.
The former UFC lightweight champion was making his BKFC debut and had not competed since April 2021 when he lost to Ok Rae Yoon in ONE Championship.
The card from Broomfield, Colorado featured several ex-UFC fighters as Ben Rothwell defeated Josh Copeland due to TKO from a corner stoppage after three rounds.
Bec Rawlings failed to win the BKFC flyweight title from champion Christine Feras, who won by TKO due to a doctor stoppage after two rounds.
Chris Camozzi knocked out Daniel Spohn at 2:00 of the opening round of their Cruiserweight contest.
