The actual foul was very close to tell. DQ seemed pretty harsh. Then again, a lot of Hoyfields pro bouts contained hitting on the break and after the bell by one combatant or the other. Make your own conclusion.
Yes, the ref was speaking English. The only language used in amateur boxing on the International level is English, and there are only 3 verbal commands-Stop, Box, and Break. All warnings are communicated with hand signals during the couree of the round.
