I didn't hear the bell watching on dazn,maybe I'm deaf though, the commentators were convinced they heard it though so maybe it was just the microphone..

although it is pretty clear on the YouTube clip there... Very bad refereeing, the Uzbek was winning and landed a good one before the bell, shame it ended iwth any controversy.

Pretty cool to see a boxing card in Uzbekistan, chubby bully Bek was on the undercard, I don't think he's too great but I find him fun to watch.
