The doctors have another look at the substantial damage done to Takam's face. He deserves to be allowed to carry on, if he wants to, and he is allowed to. On we go.

It is easy to forget on nights where Joshua is given tougher examinations, that this is merely his 20th fight as a professional.

A potentially broken nose in the second round would trouble any boxer, especially when it comes via a headbutt.

However, Joshua is in control, has scored a knockdown and the crowd are still firmly behind him. This might be a night he learns a lot against a very, very durable Carlos Takam.

Chris Boughey: Carlos Takam has some heart, remember he only had two weeks notice for this!

Callum: AJ gonna KO In next round!

Anthony Joshua must not get careless. He already has probably done enough to win this on points, if it goes that far.

Left and rights into Takam's body follow and Takam, with a battered left eye, with a battered right eye, waves his opponent on. He wants more. Insane bravery and guts from the challenger. Warrior status: granted.

Carlos Takam has only been stopped once - by Alexander Povetkin - can Joshua cause another stoppage? Remember, no Joshua fight has gone the distance. Nineteen fights, all won by knockout or stoppage.

Dennis Ethan: Takam shows some incredible resilience and is on fire in round seven.

Richard Hewitt: AJ is not looking too great in this fight....too much muscle?

Takam paws away at the cuts over his eyes, desperately trying to stop the blood from pouring out. It doesn't do much good. Joshua may well be surprised by the sheer toughness of the late substitute. Takam is doing his reputation in the boxing world a whole world of good.

Expect him to be involved in more big fights in the future.

Anthony Joshua probably has not lost a round. But one punch can change everything in heavyweight boxing.

Six gone, a maximum of six rounds left. Now Takam is cut around the left eye, to go with the cut around the right eye that he already had.

wise beso: Ref, stop the fight. Takam isn't fighting.

How much can Carlos Takam actually see in his right eye?

There is heavy swelling and the blood is dripping close to, or into his eye itself. Joshua peppers a couple of straight jabs into the Cameroon-French fighter's face and also lands another uppercut as Takam tries to attack.

An uppercut wobbles Carlos Takam. But he stays in the fight.

Anthony Joshua looks in control now and this looks to be a case of when, not if.

All credit to Carlos Takam, he has lasted a lot longer than most of Joshua's opponents and remember, he only had two weeks' notice.

Into round six, and not many expected this. Can Takam get back into this or will that cut prove just too bad?

Takam goes for an all-or-nothing wild swing. He needs to end this now with one out of nowhere punch as he looks to be in so much trouble.

His corner desperately get to work on that cut over his right eye. They need to work miracles. But Takam is one tough character.

Anthony Joshua lands two big shots to Takam's head.

Dennis Ethan: Takam in some heavy pain, lucky to not be floored in the 4th round. AJ to wrap up this in the minimum of the next 2 rounds.

Some wild swings from Anthony Joshua, both miss.

Only the bell saved Carlos Takam in the fourth. Referee Phil Edwards wants to check on that cut and see if he can carry on in the fifth. Just about, he can.
