With Mike Tyson commentating at ringside, Derek Campos picked the perfect time for a knockout finish.
There aren't too many fighters out there with more experience than Melvin Guillard, but Campos didn't back down from the veteran of 22 UFC bouts. He rocked Guillard in the first round and easily won the first five minutes of their Bellator 149 matchup.
Thirty-two seconds into the next frame, the lights went out for "The Young Assassin":

It was the most high-profile win of Campos' career and the third straight loss for Guillard. Since leaving the UFC, Guillard has struggled with his last win coming in July 2013.
