Iain Dowie welcomes back top scorer Andy Johnson for Saturday’s trip to Villa Park.
AJ sat out the midweek cup victory over Hartlepool after picking up a late knock in last weekend’s home game against Man City.
His return is a welcome boost for Dowie, after the news that a knee injury may keep new signing Nicola Ventola out for around three weeks.
Tony Popovic is also fit again after missing out against City, but fellow centre-back Mark Hudson looks set to miss out.
Villa are unbeaten at home in the Premiership and welcome back defender Mark Delaney, who missed their Carling Cup win over QPR with a stomach bug.
Probable Palace XI:
Boyce Popovic Hall Granville
Routledge Hughes Riihilahti Kolkka
