A dramatic day comes to a close as we still await news on whether Daniel Dubois will be involved on Saturday.

The IBF heavyweight champion missed today's news conference after taking ill and it's still unclear whether Joseph Parker has an opponent.

Queensberry's Frank Warren said they are waiting to hear back from a doctor and rumours are swirling that Parker could be up against a late call-up.

It was business as usual for undisputed light-heavyweight champion Artur Beterbiev and Dmitry Bivol.

Stay across the BBC Sport website for the latest updates over the next few hours.

I've spent hours today preparing Daniel Dubois and Joseph Parker content but that's all gone to waste following the news that Dubois might not be featuring on Saturday after taking ill.

I refuse to put it all in the bin, though, so here are Dubois' top five career knockouts for you to enjoy.

Joseph Parker was due to have a face-off with IBF heavyweight champion Daniel Dubois... will the New Zealander just stare off into the distance instead?!

No. He's departed the stage and, like the rest of us, is awaiting news about whether he is still fighting on Saturday.

That's it for the news conference and now for the face-off.

It's very intense but respectful between Artur Beterbiev and Dmitry Bivol.

Artur Beterbiev and Dmitry Bivol are asked for their final message.

Beterbiev says:

"Don't miss our fight. It's going to be a good fight."

And Bivol adds:

"If you liked the first fight then I'm sure the second fight won't be any less interesting. Turn on your TV and watch the fight."

Undisputed light-heavyweight champion Artur Beterbiev is asked what motivates him for Saturday's rematch:

"I want to defend my belts. Very simple."

What did he learn from the first fight?

"There are many things, it's too long to say. Let's talk after."

Would he rather take the decision away from the judges this time?

"We'll see."

More from Bivol:

"All athletes always want to win and we are like gamblers. I wasn't the winner last time but now I want that and it's burning inside me.

"I want to change something because I can see where I was wrong."

Challenger Dmitry Bivol, who is looking to bounce back from a first career defeat, is invited to have his say:

"Thank you to Beterbiev for giving me a rematch.

"I'm just thankful.

"I want to go to the ring and be a winner."

Undisputed light-heavyweight champion Artur Beterbiev is asked to respond on whether he is 'good friends' with Eddie Hearn:

"You bring me opponents and I beat them," Beterbiev says.

More from Eddie Hearn:

"Artur Beterbiev is one of the great fighters of this generation and I respect him as a champion but we want the victory on Saturday."

Matchroom's Eddie Hearn, who promotes Dmitry Bivol, is next to speak:

"I thought it was a fantastic fight the first time around.

"For me Bivol dominated for the first nine rounds. I stand by that Bivol won but that's done now and it's over. The great thing for fans is we get to run it back.

"We want to thank Beterbiev for taking the fight.

"I see something different in Bivol's eyes this week. I can't believe how well he took the defeat, he has an unbelievable mindset. I'm confident he will be undisputed champion this week and expect a fight for the ages."

Joseph Parker's manager, Spencer Brown, suggests the New Zealander will be fighting either way:

"A lot of discussions [are going on].

"Like Frank [Warren] says, he has been assessed by a doctor and we're waiting to see if it's good or bad news.

"Joe will be there on Saturday whatever happens and he's ready to win. Joe doesn't care who he fights."

Joseph Parker is asked his thoughts about the news we've been hearing regarding Daniel Dubois this evening:

"If he is ill I hope he gets better soon. I'm looking forward to Saturday and putting on a good show.

"I've put in all the hard work and I'm ready to go."

Queensberry's Frank Warren, who promotes Daniel Dubois, is first to speak with an update on Saturday's IBF heavyweight title fight between the Briton and Joseph Parker.

Warren says:

"Unfortunately, at this moment in time Daniel is being evaluated by a doctor and when we have more news we will update you and share it with you."

There was quite a delay between the first and second sections of this news conference but we're ready to go as ring announcer Michael Buffer gets on the mic.

Queensberry promoter Frank Warren and Joseph Parker have taken their seats.

Undisputed light-heavyweight champion Artur Beterbiev and Dmitry Bivol have just been welcomed on to the stage.

There is no sign of Daniel Dubois.

Wrong answers only please.
