West Ham United boss Sam Allardyce has banned contact in training due to their injury list.
Allardyce said: "Medical staff are busier than us as coaches at the moment. We can't afford any more contact or any more injuries, so we can't even do any training.
"If we try to do any training and try to do any shape or build-up for Reading, we will get contact between players and, if you get contact between players, you risk injury and we can't do that.
"We can't even get out on the field and do a bit of coaching at the moment."
