LAS VEGAS – Low blows cost Thomas Dulorme dearly Saturday night.

Referee Vic Drakulich deducted a point from Dulorme about 30 seconds into the 10th round and final round of his welterweight fight against Yordenis Ugas for repeated low blows. That point turned out to be the difference on two of the three scorecards and Dulorme lost a unanimous decision on the Floyd Mayweather Jr.-Conor McGregor undercard at T-Mobile Arena.

Judge Richard Ocasio scored the fight 94-91 for Miami’s Ugas (20-3, 9 KOs). Judges Max DeLuca and John McKaie had it 93-92 for Ugas, which means the fight would’ve been even on their cards if not for the point deduction and thus a majority draw.

The Dulorme-Ugas fight was the second of two Mayweather-McGregor undercard bouts broadcast by FS1.

Drakulich warned Puerto Rico’s Dulorme (24-3, 16 KOs) several times for hitting Ugas low before taking away a point. Ugas also complained about several shots that didn’t draw warnings from Drakulich.

Down on the scorecards, Dulorme made the fight interesting in the seventh round. He buzzed Ugas with a right uppercut with just under a minute left in it, and later knocked down Ugas with a counter left hook.

Ugas got up and survived to the end of the round.

Five rounds earlier, Ugas dropped Dulorme twice within the final 30 seconds of the second round.

A right uppercut by Ugas caused Dulorme to go down to one knee after a delayed reaction. Dulorme made it to his feet and tried to slug with Ugas to show that he wasn’t badly hurt.

A straight right hand by Ugas floored Dulorme for the second time. Dulorme got up again and the bell sounded soon thereafter to end the second round.

Dulorme got his legs back under him in the third round, which was competitive, as was the fourth round. Drakulich warned Dulorme for low blows twice in the final 30 seconds of the fifth round.

The Cuban-born Ugas took this fight on two weeks’ notice after Dulorme’s original opponent, Shawn Porter, pulled out. Porter, a former IBF welterweight champion, cited a death in his family and other personal issues as the reasons he withdrew from the fight.
