Dillon Danis was thrown out of the arena after smashing the phone of an interviewer following his first face-off with KSI.
MMA star Danis is notorious for his brash-talking antics and causing chaos at press events, having already punched upcoming rival KSI during a weigh-in for this weekend's Misfits Boxing card in Phoenix on Saturday night. The American attended the event and came into the ring with the YouTube star to announce their fight for January 14 in London.
Tensions came close to flaring up again during the heated face-off inside the ring before the pair were escorted out their separate ways by army of security. KSI returned to his seat while Danis immediately headed for the exits, but on his way out he managed to slap the phone of a video interviewer who was stood helplessly in the fighter's path.
