David Howe, the 6ft 8ins heavyweight from Sheffield, was surprisingly KO’d by an opponent more than three stone lighter in the city.
On a Dave Coldwell bill at iceSheffield, the Ingle fighter, 33, was decked by Lithuanian Davidaitis.
Howe was caught by a shot to the head and, as our video shows, stumbled towards the ropes.
In his confused state, he remained staring into the crowd as two hooks from the away fighter fizzed into his face.
He collapsed to the canvas and the match was waved off in the visitor’s favour.
Howe is now W10 L2.
