Anthony Joshua’s career as a top fighter will come to an end when he meets Kubrat Pulev, says boxing promoter Bob Arum.

The Brit reclaimed his heavyweight titles back from Ruiz in Saudi Arabia on December 7, six months after being knocked out by the American-born Mexican.

Joshua is expected to face Pulev next year following an order by the IBF. Pulev was to fight Joshua in 2017 but pulled out through injury.

And Arum, who promotes Pulev, has tipped his fighter to send Joshua tumbling back down the heavyweight ladder once again.

It looks like Joshua will have to vacate one of the heavyweight titles he has just reclaimed, with the WBO also ordering him to face Oleksandr Usyk next.

The Ukrainian, who has moved up in weight having become an undisputed cruiserweight champion, could face Derek Chisora next for the vacant belt.
