The Foxes, amongst the favourites for promotion, are currently facing an injury crisis with six first team players out of the weekend's game.
Micky Adams' depleted Leicester side travelled to Portman Road to play Ipswich last Sunday but ended up on the wrong end of a 6-1 scoreline as the Tractor Boys ran-riot.
But Cureton believes Saturday will be a different game. He told readingfc.co.uk: "Ovbiously Leicester and Ipswich are two of the favourites for the division and no-one expected a result like that - it was a bit of a shock.
"It will probably give Leicester a rocking and they'll not want to get beat against us. They'll try to put it right and might be more determined but it was always going to be a tough game at the Walker's Bowl next weekend anyway.
"It shows that they can be beaten but they'll be trying not to concede anything to us. It can give us confidence although I don't think that it will have a major affect on the ways both sides approach the game."
