def was the mouthpiece. it is a fullsize double mouthpiece made for full-size grown men, not 108 pound little guys. he even took it out in the 10th it was bothering him so much...
His mouth is open and blood is streaming and you can see a protrusion on the left side of his face.
...I think you may be right, and his fucking corner doesn't have a clue.
very possibly... though his mouth was buldging at the start of the fight... maybe his mouthpiece isnt fitted properly. o boy these lil guys are puttin on a show!
