Andy Ristie stopped perhaps the greatest kickboxer on the planet alive today, Giorgio Petrosyan, with a devastating third round knockout in the semi-final round of the GLORY 12 four-man, one-night Lightweight tournament. The loss is a first for Petrosyan in more than six years and the first time ever he has been finished. Ristie advances to the tournament final against Robin van Roosmalen.
