Norwich goalkeeper John Ruddy has been ruled out for up to three months with a thigh injury.
Ruddy, 26, picked up the injury during Saturday's 1-1 draw with Everton wand was forced to come off late in the second half. He was replaced by Mark Bunn, who is set to deputise for him for the Canaries' upcoming games.
Former Everton goalkeeper Ruddy, who has conceded just two goals in his last six appearances, had been a doubt for the trip to Goodison Park because of a knee complaint but was passed fit to feature.
The thigh injury is worse than first thought, with a scan revealing that the England international will now require surgery.
Ruddy tweeted on Wednesday: "Just to update everyone on my injury, unfortunately I have torn my thigh will be having surgery on saturday and out for up to 3 months."
The Norwich man has won rave reviews for his impressive displays since Norwich's return to the Premier League last year and was rewarded with his first England cap against Italy in August.
