George Kambosos Jr.’s Lightweight Shockwave
On November 27, 2021, George Kambosos Jr. defeated Teófimo López by split decision over twelve rounds to claim the unified lightweight championship.
George Kambosos Jr. spent years chasing a fight with Teófimo López. When it finally happened in New York in November 2021, Kambosos came as the mandatory challenger and left as the unified lightweight champion. He outworked López over twelve rounds, survived a late knockdown, and won a split decision that changed the course of both men’s careers.
The upset that made him champion
Born and raised in Sydney, Kambosos built his professional record through fights in Australia and overseas before earning the López opportunity. At Madison Square Garden’s Hulu Theater, he knocked López down in the first round. López returned the favor in the tenth, but Kambosos rallied through the championship rounds. The split decision gave him the WBA, IBF and WBO lightweight belts, along with The Ring title (Sky Sports fight report).
Defenses at home, then a new division
Kambosos faced Devin Haney twice in 2022, both in Australia. Haney won by unanimous decision each time, gathering all four major lightweight belts in their first meeting and retaining them in the rematch. Kambosos returned against Maxi Hughes in 2023 and took a disputed majority decision. His next title chance came against Vasiliy Lomachenko in Perth in May 2024. Lomachenko dropped him with body shots and stopped him in the eleventh round to win the vacant IBF lightweight title.
Moving up to 140 pounds gave Kambosos a fresh route. He outpointed Jake Wyllie in Sydney in March 2025 to earn a shot at IBF champion Richardson Hitchins, but Hitchins stopped him with a body shot in the eighth round that June. The López upset remains the defining peak of Kambosos’s career; the later results show how difficult it is to stay at the top once every contender is chasing you. Read more in our boxing archive.
Career Defining Results
Kambosos entered the López bout as an underdog but used his right hand, timing and willingness to exchange to seize the initiative. His knockdown in the opening round announced that he could hurt the champion, while his recovery from López’s late surge helped secure the judges’ split decision. The result remains the signature victory of his championship career.
