There were no excuses from Roman 'Chocolatito' Gonzalez, who was knocked out in the fourth round of his rematch with Srisaket Sor Rungvisai.
The two fought for the second time for the WBC super flyweight world title, with the hard-punching Thai boxer gaining his second straight win over the former champ.
Srisaket knocked Gonzalez down twice in the final round, finishing the challenger off with a right hook with 1:45 to go in the fourth.Gonzalez, already stunned from the first knockdown, stayed on the canvas for a couple of minutes before rising slowly and going to his corner.
The first knockdown came 42 seconds earlier when southpaw Srisaket landed a similar short right hook to the side of the head. Gonzalez was able to get up at the count of seven and continue.
"We were both trading punches, but his were harder, and they landed harder," said Gonzalez. "I was very hurt the second time when I was knocked down, but I think I'll be OK."
Gonzalez, 30, was taken to the hospital immediately after the fight for medical treatment. He was trying to avenge the only loss of his career against Srisaket but he failed to put up any defense against the onslaught of the Thai's superior punches.
He would not comment on the future of his career. Based on the way he was knocked out and giving the appearance of being a shot fighter, there were already calls for him to retire.
Srisaket silenced his critics who said his win in the first fight in March was a fluke -- the result of accidental head butts rather than his punching skills.
Both fighters came out swinging from the opening bell in Saturday's 115-pound rematch at the outdoor StubHub Center stadium, as it became apparent in the early rounds that the scheduled 12-round showdown wasn't going to go the distance.
