UFC 307 LIVE: Alex Pereira knocks out Khalil Rountree in brutal main event

In her post-fight interview, new women's bantamweight champion Julianna Pena dismissed any suggestion that Kayla Harrison is next in line for the title – instead calling on Amanda Nunes to come out of retirement for a trilogy fight to organize.

Kayla, who convincingly defeated second-seeded Ketlen Vieira earlier in the night, was far from impressed.

Conor McGregor believes he has the answer.

Alex Pereira has played down talk of an immediate move to middleweight or heavyweight after making his third successful title defense at 205.

“We saw that Dricus was going to face Sean Strickland. He’s my training partner so I don’t want to get in his way,” he said.

“I could move up to heavyweight, but this division is great. I feel great with this weight loss and here I am.”

Rountree gets worse and worse as this fight goes on. Suddenly the tank is empty.

Pereira starts the round with a stiff jab to his right eye, which pops open. The Brazilian drives forward with a vicious combination.

Poatan smells blood and places warheads on Rountree's skull. The challenger is exhausted and shoots repeatedly, violently and brutally

Rountree is drenched in his own purple and lying against the fence. He throws two seizing body shots before an uppercut finally knocks him to the mat.

The spirit of a warrior from The War Horse, but he could only take so much punishment. Pereira took no prisoners, devastating consequences. AND STILL!

Alex Pereira defeated. Khalil Rountree via fourth-round TKO (body strikes and uppercut, 4:32)

Big body shots for Rountree early in the round, Pereira responds with a head kick.

Rountree succeeds in another overhand counterattack, putting Poatan in the lead in the first half of the third round.

But as the round enters the final minute, Pereira begins to close the gap and punish Rountree with jabs. He follows with a jumping knee before initiating a clinch and throwing more knees at close range as the buzzer sounds.

We get championship rounds.
