Oleksandr Usyk vs Rico Verhoeven LIVE: Start time, undercard, fight updates and results as Catterall wins gold

Both men stand orthodox. Sheeraz has a fairly clear height advantage.

Sheeraz is immediately active, flicking out jabs, doubling them up, adding crosses.

Begic is keeping a high guard as he’s backed to the ropes. Sheeraz now curves a right hook around that guard, before splitting it with a jab.

Begic is occasionally stepping forward quite pointedly, but not throwing. Mean body shot by Sheeraz.

Now we have Hamzah Sheeraz vs Alem Begic, with the vacant WBO super-middleweight title on the line!

Good for him. What a performance tonight. A classy boxer when he’s on, and he was on tonight.

Can Catterall get a stoppage? An exclamation mark on this fight?

One-two and a right hook to the body. Now a long cross to the body. Catterall steps in as if he’s going to do the same again, but he throws high this time!

Now he splits the guard with another spearing left straight.

Giyasov backs up Catterall. He needs a stoppage now.

It won’t come in this round.

Catterall sits down Giyasov again!

It had been a comfortable round up until this point, and Catterall now drives home his superiority with a left that puts the Uzbek on the canvas for the second time tonight.
