I just watched the JML vs. Penalosa fight again with my dad since he missed it last night and I was wondering about the referee warning Penalosa multiple times to keep his head up. Is that an illegal move? Because it seemed like he was just trying to duck below shots and often times JML used his arm to keep Penalosa to one side or keep his head down, which seemed pretty smart because it looked like it bothered Penalosa or kept him from doing anything else after dodging.
