Kamaru Usman failed to retrieve the welterweight title at UFC 286 in London, losing to Leon Edwards over five rounds.
The British fighter came out on top, with the three judges scoring it 48-46, 48-46 and 47-47 in his favour.
Edwards stuffed most of Usman's takedown attempts and landed the cleaner shots in the fight.
He was rewarded for punishing Usman with a series of leg kicks, slowing the 'Nigerian Nightmare'.
Usman marched forward in his typical suffocating style, but that march became more of a hobble the longer he was sliced up.
Edwards had a point deducted during the third round for holding onto the cage, but still managed to come out on top in the huge clash.
