It’s a must-win game for both nations after opening round defeats, as Cameroon are without Samuel Eto’o and Luka Modric recovers for Croatia.
This Group A fixture kicks off at 23.00 UK time (22.00 GMT) and the losing team will be mathematically out of the running for qualification.
Brazil and Mexico both have four points, so a victory here is crucial to have any hope of catching them.
Cameroon suffered a heavy blow going into this game, as they lost star striker Eto’o to a knee injury.
The former Inter hero is replaced by Vincent Aboubakar in attack.
Croatia also have problems with Modric suffering from a bruised foot after their 3-1 defeat to Brazil, but he has been passed fit to start.
Inter midfielder Mateo Kovacic moves to the bench, joined there by Genoa defender Sime Vrsaljko.
Croatia: Pletikosa; Srna, Corluka, Lovren, Pranjic; Rakitic, Modric; Perisic, Sammir, Olic; Mandzukic
Cameroon: Itandje; Matip, Nkoulou, Chedjou, Assou-Ekotto; Song; Choupo-Moting, Enoh, Mbia, Moukandjo; Aboubakar
