Douglas Lima faces yet another grave threat to his latest reign at 170 pounds.

He last competed at Bellator 250 on Oct. 29, when he dropped a five-round unanimous decision to current middleweight titleholder Gegard Mousasi in a failed bid to become a simultaneous two-division champion. Amosov, meanwhile, enters the cage with a perfect 25-0 record. He last fought at Bellator 252, where he eked out a split decision over the previously unbeaten Logan Storley on Nov. 12.
