Jeff Saunders clinched his third pro win in Usain Bolt fashion – a lightning-quick 15 seconds.
The Sedgefield light-welterweight demolished Istvan Kiss on the undercard of the massive show at Manchester Arena.
Saunders, younger brother of championship hopeful Bradley, had won his first two bouts in a rapid time.
But this was something sensational as the Hungarian crumbled to the canvas with just the second punch of the six-rounder.
Kiss could not get up from the right to the body and was counted out by referee Mark Lyson.
