The coaching warning
Within seconds of the opening bell, Dvalishvili turned toward O’Malley’s corner after hearing coach Tim Welch shout. Dean briefly halted the bout and warned Welch. Dean later said seconds cannot interfere in the fight, influence the referee or distract the opponent. The exchange drew criticism, but no point was deducted.

Why Dean said “let’s work”
Dean also repeatedly prompted the fighters to work during grappling exchanges, including when Dvalishvili had top position. He said “let’s work” is a warning before intervention: he expects a fighter to advance position or create an opening for effective offense, not simply make busy work. Critics questioned the timing because Dvalishvili was maintaining control. Dean’s explanation, reported by MMA Fighting
A joking aside became another clip
Late in the second round, Dvalishvili kissed O’Malley on the back, then disengaged with time still on the clock. O’Malley stood and landed a punch before the bell. Dean later described the kiss as unsportsmanlike conduct and joked that it was “a little bit romantic”; he did not deduct a point. TalkSPORT’s report on Dean’s comments
