Teofimo Lopez lost his lightweight titles by a split decision to George Kambosos Jr. There is a time limit.
The opening round ended with the champion on the canvas after Teofimo Lopez promised a first-round knockout.
Saturday night at the Hulu Theater in Madison Square Garden, the knockdown was a sign of what was to come.
Kambosos, the under-seeded Australian, survived a 10th-round knockdown to score a split-decision victory over Lopez in a major upset to claim the WBO, WBA, IBF and WBC franchise lightweight championship.
One judge scored it for Lopez, while the other two judges scored it for Kambosos.
Kambosos said that he backed himself. I thought I was going to hit him hard and put him down. I can't believe how well I boxed.
Lopez said he didn't care what anyone said. I won this fight.
Lopez was fighting for the first time since he defeated Lomachenko by a unanimous decision.
Kambosos was coming off a close decision win against Lee Selby in October 2020 at London's Wembley Stadium.
