Calf injuries, especially for older footballers, are tricky ones to get over. They can easily turn into a 3-4 week lay off. WP's info comes straight from the horses' mouth, X. Kingy also mentioned that they are being cautious because he if redoes either the calf or hammy then that's season over for him. My impression is he won't play next week either.
As for changes, I reckon we'll make just the one.
