5 toughest UFC fighters that have never been knocked out

#2 Frankie Edgar

Don’t mess with Frankie

Frankie Edgar has lost quite a few fights over the years, but it's a testament to his courage and toughness that none of them has come via knockout. Frankie is one of the scrappiest and most determined fighters to ever walk through the UFC door, and it's that kind of spirit that you just can't manufacture. Seriously, go back and watch some of his best bits - they're fantastic.

We'd even go so far as to suggest that McGregor wouldn't be able to knock him out, and there aren't too many people that fall into that category. Edgar may be getting on in terms of years but his chin is still as good as ever, and if he feels healthy enough then we believe he could continue to ride this wave of success all the way towards another title shot.

We conclude with a guy who has had everything possible thrown at him.
