Anthony Joshua celebrates beating Alexander Povetkin

Anthony Joshua faces Alexander Povetkin in what the British champion has described as the "second hardest fight" of his professional career.​ Povetkin, the mandatory challenger to the WBA title, has the potential to become Russia's first ever unified world heavyweight champion, with Joshua's IBF, WBO and IBO straps on the line too.

The 39-year-old has lost just one of his 35 fights, a points defeat to the great Wladimir Klitschko in October 2013. Since then he has won eight consecutive fights, including a knockout victory over David Price on the Joshua-Parker undercard. Ominously, he has never been stopped.

Meanwhile, Joshua will be looking to extend his flawless professional record to 22-0 in his third fight at Wembley.

Okolie's reach advantage playing a big part so far. As always with the former Olympian, it was untidy but it looks as though he's taken the first round.

Povetkin has arrived at Wembley!

The WBA mandatory has a gigantic task on his hands against the 6 ft 6 Joshua this evening.

With just a couple of fights left on the night, there are still tens of thousands of empty seats in the stadium.

They're expected to fill out over the next couple of hours, but it's looking a tiny bit bleak right now.

After nine rounds of a scheduled 12, this fight between Okolie and Askin has been... poor.

You thought Okolie's bout against Isaac Chamberlain at the O2 was bad? This is even worse. Fight of the night contender turns to surely the worst fight of the year.

There's still a little bit to go, but the style of the two fighters is just making this a difficult watch for spectators everywhere.

The pair trade blows.

After 12 rounds of boxing, the final bell rings and every single spectator in the stadium boos.

We await the scorecards...

Carl Froch's scorecard has it 115-11 to Okolie, but we'll see what the judges have to say shortly.

[22 September 2018 20:34 · Adam Hamdani]

116-110

114-112

114-113

By unanimous decision, Lawrence Okolie is the new cruiserweight champion! An expected and fairly comfortable win in the end.

Next up is Luke Campbell against Yvan Mendy.

This one has a little bit of history, the 33-year-old previously defeated Campbell in 2015 - a fight that has spurred Campbell onto winning six of his seven fights since.

The winner of this will become mandatory to the WBC lightweight world title.

12 rounds coming up shortly. Let's hope it's better than what we just witnessed.

[22 September 2018 20:47 · Adam Hamdani]

Both men are in the ring and we're close to getting this one underway.

The co-main event is moments away.
