Moses Itauma - wide tipped arsenic nan early of nan heavyweight section - takes connected Dillian Whyte this Saturday successful Riyadh, Saudi Arabia.
The unbeaten 20-year-old from Chatham, Kent has stopped 10 of his 12 opponents to day but now faces nan toughest trial of his career.
Whyte, 37, has shared nan ringing pinch immoderate of nan sport's biggest names, including Anthony Joshua and Tyson Fury.
But pinch nan 'Body Snatcher' struggling for momentum successful caller years, is this nan cleanable measurement up astatine nan cleanable clip for Itauma? Or will Whyte's acquisition beryllium excessively overmuch for nan unproven heavyweight?
Saturday's bout is not only a awesome trial for Itauma - it could besides beryllium a breakout conflict against a credible, battle-hardened name.
You tin travel power and unrecorded matter commentary of nan conflict from 19:30 BST connected BBC Radio 5 Sports Extra, BBC Sounds and nan BBC Sport website and app.
We asked nan boxing world for their predictions, and present they are:
Andy Lee - retired world champion & DAZN pundit
If Whyte tin get past nan first 4 rounds past it's a fight, and it's anyone's fight. But I'm picking Itauma to win. He's a southpaw and youth, speed, powerfulness and activity are each connected his side.
Prediction - Itauma
This is nan conflict we get to find retired nan things we don't cognize astir Itauma. How bully is his chin? What does he do erstwhile he's successful nan trenches? But I don't cognize if Dillian will get nan opportunity to do that. With his inactivity, property and nan quickness of Itauma's feet, it's a nightmare match-up for Whyte.
I deliberation it's nan cleanable portion of matchmaking.
Prediction - Itauma
Zhilei Zhang - Chinese heavyweight
Itauma will triumph by KO.
Prediction - Itauma
Richie Woodhall - BBC pundit & retired world champion
I deliberation Itauma wins nan fight, but I deliberation he will beryllium stretched and he will spell past nan sixth information for nan first time.
Maybe he'll extremity him later successful nan contest, astir apt successful nan eighth aliases ninth round. It each depends really overmuch is near of Whyte.
Prediction - Itauma
Dave Coldwell - coach
I don't deliberation it's a bully 1 for Whyte astatine this shape of his career. Inactivity, age, deterioration and tear and sporadic performances complete nan past fewer years - I deliberation everything is stacked against him.
Then you look astatine Itauma - he's sharp, tin beryllium tricky to onshore on, tin antagonistic from different angles. The velocity and athleticism is nan worst benignant of force for Dillian successful this position.
Without being disrespectful to Dillian, who's a warrior and will springiness it everything he's got, I tin spot him - astatine this shape of his profession - being a sanction connected Itauma's record.
Prediction - Itauma
Anthony Crolla - retired world champion
You person to springiness Whyte in installments for taking it. He's getting good paid but location would person been different big-money fights retired location for him.
But I deliberation nan timing is perfect. I've been singing Itauma's praises since he was an amateur. At this constituent successful Whyte's career, Itauma is each incorrect for him and I deliberation it will beryllium complete successful 4 rounds. It could beryllium moreover earlier.
Prediction - Itauma
Barry Jones - BBC pundit & retired world champion
This is simply a large measurement up for Itauma. He's not boxed anyone adjacent this level. It's nan conflict we wanted to spot him in.
This is not nan Whyte of old, but Whyte knows really to resistance you into heavy waters, conflict nether unit and perpetrate to each shot. Itauma hasn't dealt pinch that yet - and that's what makes it truthful exciting.
But I do deliberation Itauma wins by stoppage. Does he person to activity for it? Maybe, but he'll triumph astir of nan rounds and astir of nan moments successful those rounds.
He'll person to deliberation much than he has before, but from nan halfway mark, Dillian will beryllium swinging and taking shots he can't spot coming. He either drops to his knees, nan referee saves him, aliases nan area throws successful nan towel.
This is nan conflict that will genuinely propel Itauma into nan speech for world honours.
Prediction - Itauma
David Adeleye - British heavyweight
It tin spell either way. People who deliberation Itauma is going to blast him retired of location are going to beryllium successful for a shock.
Prediction - sitting connected nan fence
Darren Barker - DAZN pundit & retired world champion
I deliberation Itauma is conscionable acold excessively fresh, excessively skilful and excessively speedy - and a man connected a ngo correct now. Timing is each incorrect for Whyte.
We'll spot nan youthfulness radiance through. I deliberation he'll beryllium a measurement up successful each section and gets nan occupation done successful nan 2nd half of nan fight.
Prediction - Itauma
Boma Brown - British heavyweight
I deliberation it will beryllium a bully conflict but I thin towards Itauma, who is truthful talented and riding immoderate bully momentum. I tin spot him winning by knockout aliases boxing to a points decision.
Although, I do consciousness Whyte has a bully opportunity - it only takes 1 changeable successful this division. And he does look successful bully shape.
Prediction - Itauma
Charlie Senior - Australian super-featherweight
Itauma to win. His boxing expertise and his powerfulness will beryllium excessively much. I foretell a KO triumph successful little than 5 rounds.
