Olympic champion boxerI am so happy for him. He has come from grassroots and is in the final. I am so happy
Maybe he just needs to warm up. He is like a steam train, he was flying at the end.

BBC Sport boxing pundit speaking on Radio 5 liveThere are so many expressions I could use, none of them broadcastable. He absolute whizzed that. Dychko was brilliant in the first round but by the second round Joe changed it and pulled it round and we saw what we saw.

Dychko is punch-drunk, throwing shots at thin air. He's got some space, though.

Finally, Dyckho rallies, but that's a sickening shot to the body from Joyce.

Joyce still on the front foot, Dychko walking on to red gloves. Cut under Dychko's eye. He's on all fours. A slip or a knock-down?
