Sam Allardyce will be hoping Connor Wickham doesn't come back to haunt Sunderland after the striker was passed fit to play.
Crystal Palace host Sunderland in the Premier League on Monday night.
And Eagles boss Alan Pardew has been boosted by the news that Marouane Chamakh and Wickham will take part in the game.
Both players have been put through their paces in the last two weeks in the international break and are fit enough to be involved.
Wickham completed a £9million move to Selhurst Park from Sunderland in August, having made 40 appearances in all competitions last season for the Black Cats. His time at Selhurst Park so far though has been plagued by injury, restricting him to just four appearances.
Pardew said: "We've had one or two players coming back to us.
"Wickham and Chamakh will be involved, along with all those from Liverpool.
"Gayley's still out. It's possible that Sako may not train tomorrow. But, as I say, Wickham and Chamakh are back."
Sunderland boss Allardyce has a good record in games against Pardew, winning six of the 13 games the pair have contested so far.
And former Newcastle United manager Pardew is expecting a difficult evening at Selhurst Park.
Pardew added: "I never fancy my chances against a Sam Allardyce team, because of his knowledge.
"They'll give everything they've got to get the victory.
"Sam knows that both those clubs up there are everything to the fans, so he'll be looking to get them up and running.
"He's a great choice for Sunderland."
