Artur Beterbiev vs Dmitry Bivol LIVE: Start time and round-by-round updates as two champions headline to secure undisputed light heavyweight world title

Cameron is successful with a right hand over the top and the fight is briefly interrupted as Whittaker retrieves his mouthpiece.

We've seen Whittaker find his rhythm and flow many times, but Cameron just wouldn't let him.

Whittaker is cautioned for striking from close range, but Cameron responds again with hard shots in the middle of the ring.

Both fighters had made it through the top round as the bell rang to end the round, with Whittaker appearing to be in extreme discomfort.

Surely the fight won't end this way, right?

Experience is an extremely valuable asset for any fighter, and Cameron has so far proven that he is capable of giving the fight to his opponent.

Cameron is cautioned by the referee for pressing his forearm to break the clinch, but immediately resumes his activity.

The former Commonwealth champion makes this fight ugly and succeeds by landing short shots from the inside.

Cameron is once again lively from the first round, but is stung by a stiff right hand on a counter from Whittaker.

Whittaker's defense has been doing well so far, but we haven't seen the skills that have made him so popular yet.

I think he realizes that Cameron is giving him a much tougher test than many anticipated before the fight.

The way Whittaker turns around is truly something to behold…

Headshots are proving difficult for the Shefiled fighter, but Cameron wisely targets the body in an attempt to score some points for himself.

Whittaker lands a quick three-punch combo and stops to admire his work, which is met with a decent response from Cameron.

A better round than the weaker one, but Whittaker outdoes it with his activity.

The first of our ten rounds is underway and Whittaker immediately takes position in the center of the ring and begins probing with his jab.

Whittaker clearly has the speed advantage here, but Cameron is no slouch and remains compact.

He'll need to maintain a good guard as Whittaker continues his quick, straight punches.

Speaking of prospects…

While his in-ring actions have been divisive at times, you'd be hard-pressed to find anyone who would argue that Ben Whittaker shouldn't be watched.

To the uninitiated, Whittaker's unconventional style is almost contemptuous of his opponents in a way reminiscent of the famous Prince Naseem Hamed.

Tonight, the Olympic silver medalist faces perhaps the toughest test of his professional career as he prepares to face former Commonwealth champion Liam Cameron.

In the second fight of the evening, we have the second victory of the debutant, and Mohammed Alakel unanimously defeats Jesus Gonzalez based on the judges' scorecards 40-36.

The Saudi prospect honed his skills under the tutelage of respected coach Joe Gallagher and received an enthusiastic reception from the crowd when he entered the Kingdom Arena.

His hard work seemed to have paid off as he seemed completely unfazed in this situation and consistently outworked his Colombian opponent throughout the four rounds.

Alakel undoubtedly still has a long way to go, but if this performance is any indication, he has a bright future ahead of him.

Today's fight is already underway and in our first fight, Marco Maric defeated Christian Lopez Flores by decision.

All three judges gave the Swiss fighter the nod 40-36.

It could be said that this was his first fight as a professional, Maric looked comfortable on the big stage, cutting well across the ring and forcing his opponent into the ropes.

He may have been outnumbered, but Lopez Flores was a lively opponent throughout and showed why he has a hard time finishing despite suffering 46 defeats in his career.

If you can say anything about extra-curricular activities related to the season's events in Riyad, no expense is spared when it comes to the promotional side.

Have you ever wanted to see two of the world's most dangerous warriors leading armies into medieval battle?

Both fighters in tonight's fight made the 175-pound light heavyweight limit on Friday, but Beterbiev had to go to some pretty extreme measures to do so.

The 39-year-old went on a fluid-only diet for three days before stepping on the scale and told Mail Sport's JEFF POWELL MBE he would take advantage of his hunger in the ring.
