Tyrone Spong suffers broken leg on kick at Glory 15 (GIF)
Spong is a Muay Thai/kickboxing expert who also fights in MMA. He was facing Saki in the Glory 15 Istanbul light heavyweight world championship kickboxing tournament and lost when he attempted a kick with his right leg and had it checked by Saki. His shin shattered.
It was very similar to what happened with Anderson Silva when he lost to Chris Weidman in December.
Spong is now 74-7-1 in his kickboxing career, which is still pretty darn impressive. This was the finals of the tournament.
