Dikgacoi doubt for Palace
Crystal Palace midfielder Kagisho Dikgacoi is doubtful for the game at Portsmouth due to a thigh injury.
The South Africa international was forced out of the weekend home draw with Ipswich during the first half and replaced by Owen Garvan.
Manager Dougie Freedman has no other new injury or suspension problems, but midfielders Mile Jedinak (groin) and Jonathan Williams, plus defender Anthony Gardner (both hamstring) are all out for the remaining three games of the season.
Jonathan Parr and Kyle De Silva are pushing for places in the starting line-up after stepping off the bench against Ipswich, while fellow midfielder Stuart O'Keefe is hoping to keep his place.
Strikers Glenn Murray and Jermaine Easter could return to contention after missing out altogether in the last two matches.
