Norwich City boss Dean Smith admits goalkeeper Tim Krul has suffered a major injury.

Dutchman Krul, 33, suffered the injury late on during the victory over Everton on Saturday and Norwich are awaiting confirmation of how long he will be unavailable.

"Tim Krul is out. He hurt his shoulder, the ACL joints, in the last minute of the Everton win," said Smith, whose side travel to relegation rivals Watford on Friday night where Angus Gunn is expected to deputise in goal.

"I am not sure on the time with him at the moment. He went to see a consultant yesterday, so I am waiting for the feedback from our medical staff to give me some time on it.

"He will be a big loss as we saw when he missed the two games against Arsenal and Crystal Palace, but when those big players come out of the team and are a loss then it is an opportunity for others."
