Wilder said: "We’ve had some disappointing news regarding Ryan."
Wilder said: "It was the same spot that he got the initial injury, so a recurrence of that."

Bamford assessed after shoulder problem
Bamford is expected to be available after suffering a shoulder problem against Derby County.
Wilder said: "I said after the game for a centre-forward just after he scored to come off in that period of the game, shows it was a big bang."
