Did Cerrone blow his nose on purpose ? Probably... but if that's the case, it's a shame because he still had a chance, he could have gotten a lucky shot and won in the last round. Ferguson was the better fighter though.
I didn't really enjoy the fight anyway. Those guys are not kickboxers god damnit ! One miserable attempt at a takedown, only one ! Not my kind of fight.
Hard to say if Cerrone did intentionally blow his nose though. Maybe he can't breath when we was hit in the nose and subconsciously blow it.
It was a good fight though, I think Cerrone did good in the first round, but Tony was such a bad ass and he keeps on coming and his work rate is insane.
though they have been advised not to do that, the urge to blow is just irresistible when you are in that situation. probably unintentional but consequences are still there. the people who pay wants a knockout but donald blew it away.

finishing up all 5 rounds would have been satisfying. i think he'd rest for now before given another chance considering what he'd done.
For me this is a very pleasant battle with only 5 rounds with painful blows to blow up the nose, I think it might be in the form of revenge to secure the match situation, whether intentionally or not it's his business, all that is done is always the consequences but don't too thought about because this is a very strong match.
