Watch: Paulo Costa strongly disagrees with referee Jason Herzog after point deduction for eye poke against Marvin Vettori

Paulo Costa wasn’t happy on Saturday night when Jason Herzog opted to take a point off of him due to an eye poke in his bout with Marvin Vettori.

The fans seemed happy with the decision given how many times he’d been warned, but Paulo Costa himself felt otherwise.

Check out the video below:

Costa can be heard saying “no, no, no” upon realizing that Jason Herzog was going to make it official. It almost seemed as though he thought he could alter what was happening.

Paulo Costa and Marvin Vettori went to war in Las Vegas, producing one of the most entertaining main events of the year as they looked to settle the scores. Vettori came away with his hand raised and the victory, whereas Costa was left to reflect on his decision to have the fight take place at light heavyweight instead of middleweight.

Light heavyweight future for Paulo Costa?

In his post-fight press conference, UFC president Dana White made it fairly clear that he wants to see Paulo Costa fight exclusively at 205 pounds moving forward. He seemingly made the decision on the basis of what went down during the week, but Costa's team insisted that he does want to keep going at middleweight.

The one big difference that many noticed was his improved gas tank. Paulo Costa isn’t known for being a cardio king, but even in the final round, he was really going after Marvin Vettori. He may have even come close to stopping him on one or two occasions.

Light heavyweight is viewed by many as a division in rehab, with new youngsters attempting to come through and change the status quo.

If Paulo Costa commits to the move, it’ll mark an important shift in his career.
