Mike Tyson's words of wisdom to Anthony Joshua as he's hit with boxing suspension

Mike Tyson's words of wisdom to Anthony Joshua have re-emerged amid the boxing star's boxing suspension.

Joshua has been hit with a suspension following his devastating fifth-round knockout defeat to Daniel Dubois at Wembley Stadium.

He fell short in his bid to become the IBF world heavyweight champion, which would've made him a three-time world champion.

In wake of the fourth defeat of his professional career, the British Boxing Board of Control have handed Joshua a medical suspension, ruling him out of any boxing action for just under a month, according to the Association of Boxing Commissions and Combative Sports.

Once the suspension is lifted, 'AJ' is free to resume training ahead of potentially rematching Dubois.

It's not his first setback, having suffered defeats to Andy Ruiz Jr and Oleksandr Usyk (x2).

And when Joshua had to bounce back from his previous defeats, Tyson told him not to get 'discouraged' as he issued a message to the Brit.

Asked to give advice to the former world heavyweight champion, 'Iron' Mike replied: "That he has a lot of talent and not to get discouraged

"He only loses when he quits. When you quit all the doors or opportunities close."

Tyson added: "You know, you've just got to be... you have to be game and in until the finish.

"Don't get discouraged if you lose. You just lost, you may have got $30 million.

"I just think the more you... the more time you lay off, the worse you get. You have to fight constant. To be the best, do it more and more and more."

Joshua's crushing defeat to Dubois snapped a four-fight winning streak that included victories over the likes of Otto Wallin and Francis Ngannou.

He goes back to the drawing board ahead of potentially running it back with Dubois.
