Francis Ngannou was almost forced to pull out of his fight with Ciryl Gane after "blowing his knee out" three weeks from the bout.
Ngannou made his first world heavyweight title defence at UFC 270 against the unbeaten Gane, taking a five-round unanimous decision victory to unify the division.
Gane had been made interim champion last summer when he defeated Derrick Lewis at UFC 265, and had never lost in MMA prior to last night's bout.
