Paulo Costa and Luke Rockhold on Saturday at the Vivint Arena in Salt Lake City
The co-main event of UFC 278 delivered a wild, Wild West-style bar brawl.
After about 20 seconds, Rockhold reversed position.
And then the blood on his face began to rub off on Costa's face.
When a replay was shown on the video board inside the arena, the crowd grew,
But it was just one crazy moment in a wild fight.
Costa won on all three cards with a score of 30-27,
In which the men hit each other repeatedly with kicks and punches.
Rockhold spent the last half of the fight mainly hanging against Cage.
Because he was very tired, but every time he threw a kick or punch, Costa would get hurt.
When it was over, Rockhold took off his gloves.
He hugged UFC broadcast analyst Joe Rogan,
He kissed Rogan on top of his head and left his blood on Rogan's white shirt.
He was emotional as the former Strikeforce and UFC middleweight champion decided to retire.
