Joe has got to play just how he played that round, he is giving him no room to work. Joe is slowing Dychko down. 

I want him to continue that in the third round.

Joe is a five-round fighter.  He is just warming up but this will be the most important 180 seconds of Joe's life. Joe has to get straight at him in this round.

The second round given to Joyce, all across the board. Level after two, decisive third coming up.

Dychko's movement is slowing to that of a glacier.

Dychko has slowed, almost like a statue. There's the bell. Surely that round went to Joyce?

Joe has got to keep working.

Joyce keeps coming, ever closer. Dychko on the ropes.

Dychko is hurt! He's open-mouthed, drinking in the oxygen. Some clubbing punches from Joyce.

Balder the Brave: Joe Joyce is the spitting image of Muhammad Ali. Has more timber but moves like an attacking Ali.

Joyce is getting closer early in the second round. Body shots, upper cuts by the man in red.

I think the GB camp would have expected Joe to lose the first round.

He has got to slow his man down and win this second round.

The judges give the first round to Dychko. All three have Joyce 10-9 down.

I went to the wrestling this morning and I can assure you that was a legal freestyle move.

What's gone on here? Both men are down, losing balance after a cuddle. That's a lot of meat falling. Tremors felt in Chile. End of the first round.

You can't help but be nervous and GB have had tough draws from the get go. 

Joe handles me in sparring very well and I have beaten Dychko. Joe has spared with him and I hope he has a good mindset. 

As long as he has got his mind right, it should be a good night for him.

Lots of noise in the arena, Joyce on the front foot, jabbing with the left. Dychko is fleet of foot, dancing.

Anthony Joshua
Olympic champion boxer on BBC One

The guy Joe is boxing has an unbelievable jab.

He was in 2012 as well, has filed out a lot more, it will be interesting to see the development since then.

Already halfway through the first round for Joe Joyce against Ivan Dychko. This a semi-final. Win and it's the final, lose and it's bronze.

Lutalo Muhammad, a bronze medalist four years ago, is through to the Olympic semi-finals. He fights again at 21:15.

Two kicks land for Muhammad! He leads 8-1. Surely he's through.
