Anthony Joshua will take on Carlos Takam at the Principality Stadium in Cardiff, Wales on Saturday night with all three of his world heavyweight titles on the line.
Originally, AJ was set to face the mandatory IBF challenger, Kubrat Pulev. However, a pectoral injury opened the door for the 36-year-old Takam to step into the breach just last week.
Takam has some big fight experience having taken now-WBO champion Joseph Parker the distance and stepping inside the ring with former world champion Alexander Povetkin.
Takam lost on both occasions, but he enters this fight with Joshua with nothing to lose and the WBA, IBF and IBO straps to gain.
The Cameroon-born heavyweight is noted for his no fear style inside the ring and there is no doubt he will be willing to trade shots with Joshua.
Sky Sports pundit and former cruiserweight champion of the world, Johnny Nelson, believes the late switch in opponents could 'spook' Joshua.
"Fighters get spooked by silly little things, like not being the last man out of the changing room, not putting their boots on properly, things like that," he told Sky Sports News.
"I think this could be spookier for Joshua.
"When you get an opponent in at the last minute you know that if you are at the top of the tree, they know what you're like, what you're good at."
Quite a bizarre statement, really. Yes, Joshua would have been preparing for Pulev and Takam is very different, but likening the situation to not being the last out of his dressing room doesn't make a great deal of sense.
Nelson went on to say that he believes Joshua is lucky Takam took this fight late and he does not have a full training camp behind him.
"If he (Takam) had more notice, I think this would've been a harder fight than Pulev," Nelson said.
"He's an attacking fighter, he's very cool, very calm and very matter of fact, and he's not intimidated by it all.
"Yes, he's frustrated he hasn't had more notice for this particular fight, but he says 'you will see what I can do'."
So, Takam could spook Joshua because of the timing, but AJ is fighting him at the best possible time? Got it.
