Palace to wait on Smith
Former Southampton forward Ryan Smith who was released at the end of last season has been on trial at Selhurst Park.
But Palace boss Warnock has to wait to judge Smith after the player suffered a hamstring injury.
'We've had Ryan on trial here - but he's pulled a hamstring so we can't have a proper look at him at the moment,' Warnock told the Croydon Advertiser.
'We think he will be out for three weeks, he is still with us so we will have a look at him once he's playing.'
