This was night of horror cuts in UFC!
Well done Sandhagen for deserved win, but Song's face was messed up in this fight, and Gregory Rodrigues face was much worse from fight with Chidi Njokuani.
Dana White shared before and after operation photos and I think you can see Rodrigues bones and brains, but he won this fight

Better watch full main card again if you want to see how this happened.

I was horrified watching both cards, there were so many bad injuries. Rodrugiez is a really crazy guy, he got a knee hit on the head while he was double diving in the first minutes of the game, and that knee slash left him with a cleft. It was probably the worst I've ever seen, but the referees said they didn't finish the match, it could continue. Then he managed to beat Njokoan in the second round, what a comeback. He fights so professionally that I never felt uneasy, despite the bloodshed.
The same injury occurred in the main card match, Song was badly injured. He had a large opening in his brow. Sandhagen easily pass his opponent's guard with elbow strikes. Song took a lot of elbow hits. Song is a strong athlete, but it was very easy for me to predict what he will do, it would be better if he created a different style.
