You can listen to exclusive live commentary of Anthony Joshua v Carlos Takam on Saturday, October 28 only on talkSPORT
Back in April, Anthony Joshua established himself as the number one heavyweight in the world by scoring an 11th round technical knockout over former long-reigning champion Wladimir Klitschko at Wembley Stadium.
AJ unified the WBA and IBF belts in a fight for the ages in front of 90,000 people, but now has to get back to business as the time has come for him to make a mandatory defence called by the IBF.
His original challenger, Kubrat Pulev, was forced to pull out through injury, so Joshua will now tackle Frenchman Carlos Takam in Cardiff.
Here is everything you need to know about the contest…

Anthony Joshua v Carlos Takam will take place on Saturday, October 28 at the Principality Stadium in Cardiff. The reason for this is because the 74,500 capacity stadium has a retractable roof and so can put on a huge indoor show in the autumn months.
