Crystal Palace will be without four defenders for Saturday's trip to Manchester United.
Roy Hodgson confirmed Gary Cahill, Patrick van Aanholt, James Tomkins and Nathan Ferguson will miss the Eagles second game of the season.
"We are starting to get players back from injury," Palace boss Roy Hodgson said.
"Mamadou Sakho, of course, is the latest to be able to take part in training sessions. Christian Benteke and Connor Wickham took part in today's training session, albeit with Connor it was more modified than with Christian.
"We hope also that Jaïro Riedewald will train tomorrow – he didn't train with the first-team today – but we hope he will tomorrow having recovered from the injury he picked up last week."
