Rising star Bo Nickal dominates and wins by second-round submission at UFC 300, so why was the undefeated middleweight booing HIMSELF afterward?

Bo Nickal indicated he was unhappy with his performance despite extending his unbeaten record at UFC 300.

The former collegiate wrestling star got off to a flying start to his professional MMA career, but faced his toughest test yet on Saturday in the form of UFC veteran Cody Brundage, who competed eight fights.

From the opening bell, Nickal wasted no time using his grappling hook to force Brundage to sit down and establish a dominant position.

However, unlike some of his previous opponents, Brundage managed to hold his own against the onslaught of submission attempts and the packed house at Las Vegas’ T-Mobile Arena made their feelings clear when a stalemate ensued .

Despite being forced into the second round for the first time in his professional career, Nickal was no less dominant in the next frame as he again earned an early takedown.

But the 28-year-old seemed unhappy with his performance at UFC 300.

This time, Nickal would leverage his positional dominance. The All-American wrestler took his opponent’s back and locked in a rear-naked choke with more than a minute remaining in the round.

Immediately after getting the tap, Nickal appeared to indicate that he was unhappy with his performance and waved to the crowd.

Speaking inside the Octagon after raising his hand, the 28-year-old insisted the fight had been a good “learning experience”.

“I expected to dominate and completely shut this guy out,” Nickal said. “I was able to experience doing more than one ride. I think he was more confident and came out to fight, it’s a good learning experience, I guess I could have been more tactical.

“I am grateful to everyone who supports me and to those who don’t, you will all love me, I guarantee it.

“I want to fight a better guy every fight. I’m 6-0 now and most of the guys I fight are 16-20 fights old. Anthony Hernandez is a guy I could fight, if you get the call to fight me just be grateful and sign the contract.

Nickal insisted that reaching the second round for the first time in his career was an important learning experience.

Khamzat Chimaev made his feelings about Nickal’s performance clear in a social media post

One man who was clearly unimpressed with Nickal’s performance was his compatriot Khamzat Chimaev.

The two undefeated men have exchanged barbs in the past and Chimaev appeared to reignite their feud in a social media post, writing: “That fight was a bitch.”
