Multiple people with knowledge of the promotion’s plans confirmed the fight is off for undisclosed reasons. UFC Vegas 64 takes place on Saturday at UFC APEX in Las Vegas.
Contender Series Alum Almeida has struggled mightily with cancelled fights, previously losing one date with Grishin before losing a pair with Shamil Abdurakhimov. In total, he’s seen five bookings fall through.
Grishin signed on to meet Almeida a second time after a booking at UFC Vegas 55 was scrapped. He most recently appeared in the octagon at UFC 271, where he won a decision over William Knight. But three subsequent bookings have fallen through for the Russian.
