No excuses this time. UFC Welterweight champion Kamaru Usman put an end to his rivalry with Jorge Masvidal in the most resounding way possible in UFC 261 on Saturday.

The Nigerian Nightmare gave Gamebred his first knockout loss inside the Octagon in the main event of UFC 261 at VyStar Veterans Memorial Arena in Jacksonville, Florida.

At the 1:02 mark of the second round, Usman landed a haymaker of a right hand that clocked the challenger right in his jaw. Masvidal, who is usually on the giving end of these knockouts, was clearly unconscious right before his body hit the mat. The WW champ hit several follow-up hammer fists for good measure before referee Herb Dean could mercifully stop the contest.

Now that was clearly a statement win for Kamaru Usman, who is slowly building his case as the UFC's current pound-for-pound champion.

Although Usman entered as the betting favorite in UFC 261, it was clear that the Jacksonville crowd was pro-Street Jesus since he also resides in Florida. But it did not deter Usman one bit, as he executed his game plan to perfection and beat Masvidal in his own game.

After the match, Jorge Masvidal admitted he didn't feel Usman's power in their first fight and expected a wrestling-heavy bout. He gave props to the champion for catching him by surprise and even graciously admitted that Usman was the better fighter in their UFC 261 showdown.

The win, meanwhile, marked Usman's fourth successful title defense and pushed his winning streak to 18 wins (14 of those in the UFC). By the looks of it, Usman is already cleaning out his division. Who's next for the Nigerian Nightmare?

It also perfectly capped a wild night for the MMA world, which saw Chris Weidman suffer a gruesome injury in his fight against Uriah Hall.
