Anthony Joshua is back in action for the first time this weekend since his career-defining fight against Wladimir Klitschko last April.
The 28-year-old became the WBA, IBO and IBF heavyweight champion that night and was set to face Kubrat Pulev in Cardiff with his titles on the line this weekend.
Unfortunately, Pulev pulled out of the clash with a pectoral injury and Carlos Takam has stepped into the breach.
Joshua will have to change his gameplan completely for the style of Takam. He was training for the rangy style of Pulev, but Takam is a fighter that prefers to get on the inside.
Also, while Joshua is 6'6" and Pulev is 6'4", Takam is listed as just a shade under 6'2" which gives AJ a noticeable edge in height and reach at the Principality Stadium.
Ahead of the bout, Joshua laid out exactly how he plans to defeat the 36-year-old Frenchman.
The world heavyweight champion said: "With Pulev it wasn't about whipping him around the body, it was about staying off the line and boxing down the middle. Carlos is different - he can trade down the middle. My speed will beat his combinations. A good way to beat Carlos is to take his body out, that's what Povetkin did to him."
Joshua added: "[Takam] moves around a lot, and boxes well. As the rounds start going on he likes to trade, and throw hooks on the inside.
"I've had sparring partners who have tried to knock me out, and I've had to dig in and give them some body shots. So my inside game has definitely improved. If we stand on the inside and start trading, it will be entertaining."
Takam has only been stopped once in his long career - at the hands of Alexander Povetkin - and he only has three losses in 39 fights.
Conversely, Joshua has never been stopped and he has won all 19 of his fights via knockout.
Something has to give in Wales on Saturday night and the onus will be on AJ to score a KO. However, Takam went the distance with WBO champion Joseph Parker last year, so he'll be no walkover.
