I err on the side of brain fart. With it being an awkward position and them fighting position with their lower body.
Even though I think it wasn't intentional I could have seen the case for a point deduction because it was a decent kick and opened up a cut.
It would have been unfortunate to have fight end in a draw. If they were going to be strict about fouls in the fight then Warren would have lost the point but I also believe Dantas would've lost a point by the 2nd round for the cage grabs.
I think the rematch is inevitable either way. It was a great competitive fight but not hard to score.
