Port Vale forward Anton Forrester has been ruled out for three weeks with a hamstring injury.
22 year-old Forrester who has two goals in four starts injured the same hamstring that ruled him out of action earlier in the season.
Assistant manager Michael Brown said: “It’s a hamstring again, we don’t know exactly yet how bad it is but it is the same hamstring so 100 per cent it will be a few weeks. So, we have to be extra careful with it. He did everything right, came back did his rehabilitation, but it has broken down again.”
