viktor jurk vs edwin castillo

The Viktor Jurk vs Edwin Castillo fight really shocked many with the sheer power of the knockout and speed of it that was seen.

Literally the bout just started on Friday night and within the first punch it was basically over.

Here’s what happened:

  • Fight: Viktor Jurk vs Edwin Castillo
  • Date: May 15, 2026
  • Venue: SAP Arena, Mannheim, Germany
  • Result: Jurk won by 1st-round KO
  • Time: ∼3-5 seconds, not officially timed

So all in all, it didn’t beat the record but it certainly got close.

Despite what it looked like, it didn’t set the record but what a shot though.

A great win for Jurk and for those new to boxing who don’t know him, here’s who he is:
