Zolani Tete knocked out compatriot Siboniso Gonya in 11 seconds on Saturday night - setting a new record for the quickest ever world title fight.
At the Belfast SSE Arena on the undercard of the Carl Frampton vs Horacio Garcia bout, Tete dispatched his South African countryman Gonya in incredible time to retain his IBO Bantamweight title.
After a fierce right hook six seconds in, Gonya was left unconscious on the ring floor. The official then waved away the contest after another five seconds, Gonya later had to be treated with an oxygen mask.
"I've been preparing so hard for this fight. I knew Gonya wasn't going to last," Tete said. "I won in the first round! My trainers are the ones doing the job behind the scenes, I would like to thank them.
"I would love to fight Ryan Burnett. I believe he stays here, this is his hometown, so we should see who is king of the bantamweights."
The previous knockout record holder was ex-WBO super-bantamweight champion Daniel Jimenez, who swept aside Harald Geier in 17 seconds 23 years ago.
Zolani Tete now holds a record of 26 wins from 29 bouts and seems hungry for his next potential challenger - Ryan Burnett.
