Alexander Volkov put the top tier of the heavyweight division on notice with a fourth-round knockout of Fabricio Werdum in the main event of UFC Fight Night 127 from the O2 Arena in London.
Vai Cavalo wasted no time in getting right to work against Volkov. He immediately ran across the cage and threw a flying side kick before grabbing onto a leg and dragging his opponent to the mat.
The Russian eventually worked his way back to his feet, but not before Werdum was able to do damage on the ground. Volkov landed some hard strikes, but Werdum once again forced him to the mat and did enough to win the round, per Bloody Elbow:
