"Murty's got whiplash injuries to his neck and went to hospital as a precaution," explained Fearn, the physio, speaking to Teamtalk.com.
"We will not know how bad the whiplash injuries are for a couple of days. It can be a few days, a few weeks or even months, it's difficult to say so we'll have a look at him over these few days.
"It is not inconceivable that he could return to the team as soon as Saturday.
"Martin Butler was fine, he had a bit of a headache after banging his head, but he is OK."
Murty will have to wear a neck brace for the next couple of days before seeing a specialist on Thursday.
Yesterday lunchtime as Martin Butler drove his team mate Graeme Murty home from training in his Mercedes they collided with a large van on the A340.
Speaking after the accident a shaken up Murts said: "I was looking the other way so I didn't actually see it (the collision) happen. I was just thankful that no-one was hurt."
Eager to home, last season's Supporter's Player of the Year was stopped by paramedics.
"The paramedic said that with the symptons I had letting me go home was more than his job was worth. Fair play to him, he did his job very well," Murty added, speaking to readingfc.co.uk.
