#1 versus Fabricio Werdum - UFC Fight Night 127 (March 17, 2018)
Derrick Lewis should be worried. In his most recent bout to date, Alexander Volkov delivered the greatest performance of his career, notching up the biggest win of his career as well.
Former UFC Heavyweight Champion, Fabricio Werdum was the Russian's sternest test to date. The man who ended the legendary Fedor Emelianenko's 28 fight unbeaten streak was looking to put himself back in Heavyweight Championship contention.

However, Werdum hadn't reckoned on Volkov's superior performance.
The fight initially went to plan for Werdum as he kept control of his younger opponent with his ground and pound game.
However, the longer the fight went, the more fatigued Werdum got and by round 3, it was clear he was going to need a miracle to stop Volkov. Volkov grew with each passing minute and landed a devastating knockout in the fourth round to seal the victory.
