You’re 18 and you’re about to do battle on the biggest boxing stage there is – the Olympics!

Spaniard Valentin Loren stepped into the ring with fellow featherweight, Hung-Cheng Hsu of Taiwan, but ended up having a bigger fight with the other person in the ring.

There are very few details about Valentin, Hsu or this first round fight at the 1964 Tokyo Olympics. According to the press on October 14, 1964, Loren was “consistently fouling” the Taiwanese boxer, and the Hungarian referee had seen enough. In the middle of the second round, the referee, Gyorgy Sermer, suddenly disqualified Loren.

Furious upon understanding that his Olympic career had been stopped only minutes into it, Loren began chasing Sermer around the ring before landing a few punches. Loren’s left hook to Sermer’s face, likely Loren’s best punch of the night, was plastered in newspapers around the world.

That day, the Amateur International Boxing Association executive committee met in an emergency meeting. The room must have been tense as the committee actually brought Loren and Sermer together before declaring a ban on Loren from Olympic and amateur boxing competition for the rest of his life.
