Joe Cole will have a scan on his hamstring injury later today. Cole had to be subsituted yesterday after feeling a tweak in his hamstring. The midfielder will undergo a scan at Melwood to discover just how serious the injury is. "Joe has a slight hamstring injury so he will have a scan tomorrow," said Roy Hodgson. "Hopefully he will be ok but I can't say how long he will be out until we get the results of the scan. "Often these muscle injuries always seem to take ten days to two weeks, but I know Joe will be keen to be fit for Chelsea next weekend. We'll have to wait and see."
