Oseni (8-1) steps in to replace Joey George in the title bout. Born in Nigeria, Oseni moved by himself to Canada at the age of 11 and now lives in Toronto, Ontario. Oseni, who has previously trained in the Netherlands, has won four of his last five matchups, including victories in Holland and Mexico. Tramell (8-2) makes his long-awaited organizational debut as the heavy hitter from Austin, Texas, completes his comeback from a devastating motorcycle accident suffered while competing in Thailand.

For Diop (2-0), his clash against Peacock marks his return to Lion Fight. Now fighting out of Fort Lauderdale, Florida, U.S.A., Diop notched a pair of knockout victories in his initial foray with the promotion, beginning with a second-round TKO of Trevor Ragin at Lion Fight 37. He followed that up with a head-kick knockout finish over Hero Vincent at Lion Fight 46. Peacock, who is originally from England and now fighting out of Calgary, Alberta, Canada, and competes with just one fully developed arm, has blasted through his previous rivals. Most recently, Peacock scored an impressive knockout win over Lee Walton at Lion Fight 62 in Dublin, Ireland.
