A shattering knockout punch left a heavyweight fighter needing oxygen and lying on the floor for several minutes.
Brit Fabio Wardley, who is trained by global heavyweight star Dillian Whyte, went up against Richard Lartey. It was believed to be a huge test for Wardley up against the Ghanaian heavyweight.
Wardley was second best in the early stages of the first round as Lartey managed to clip the Ipswich Town native. But things flipped come the second round.
The 25-year-old exploded, landing a huge knockout punch that thundered Lartey and sent him to the floor, where he laid still for several minutes.

Lartey remained on the floor before being helped onto a stool safely when he spent a further few minutes recovering.
British boxing great Tony Bellew took to Twitter to show his amazement at the win for Wardley, calling it a "statement".
Wardley told The Sun after the bout, he was happy with the result that 'answered questions about his punching power'.
"I can hang with the big boys. I just proved that when I sit down on my punch, I can get you out," he said.
"I'm moving at a good pace. Decent opposition. Lartey was a good challenge that I passed easily.
"I still need to build and learn. I haven't gone to the second half of a fight or got into a war."
Wardley now has a 10-0 professional record, with nine of those wins coming via knockout. He currently holds the English heavyweight title.
