League leaders Leicester City have a tough job on their hands to keep their 100% home record after conceding twice in the opening half against Crystal Palace.
The home side began the stronger and were twice kept out as David Nugent and Anthony Knockaert tested Julian Speroni.
Palace came into the game after the 15-minute mark and Jonathan Parr forced Kasper Schmeichel into a save before the visitors took the lead.
Schmeichel couldn't hang on to an Owen Garvan corner and Damien Delaney rifled home his third goal in four games.
Delaney's centre-back partner Peter Ramage got the second by meeting Yannick Bolasie's corner.
