A busy year of mixed martial arts wraps up this weekend with UFC 219 and the RIZIN FF World Grand Prix: Final Round, but there are plenty of highlights to look back on. 

While we look back at 2017, some of the most memorable knockouts inside of the cage have come from the UFC. You have Francis Ngannou decapitating Alistair Overeem, Edson Barboza destroying Beneil Dariush with a flying knee and a vicious elbow from Mike Perry against Jake Ellenberger. 

But what about some of the top knockouts you may not have seen?

We’ve scanned the web for 10 of the most under appreciated and under the radar knockouts from the past year that you need to see before the curtain closes on 2017.
