Norwich City wide player Onel Hernandez is expected to be out for a minimum of three months after damaging his knee climbing the stairs at home, in a gloomy injury bulletin from Daniel Farke ahead of Newcastle’s Premier League visit.

The Canaries' head coach revealed at his pre-match press call on Friday at Colney Hernandez had suffered a meniscus tear and is set for surgery on Monday.

The Cuban is poised for a scan later on Friday to assess the full extent of the damage, and Farke admitted it is a body blow.

"A big blow," said Farke. "It sounds a bit funny but the result is pretty horrible for us. He slipped at his flat on the stairs and fell on his knee. It is definitely a lateral meniscus tear. We will wait for the scans but we are 95pc certain.

"We also have to check if there is something with his ACL. The first diagnosis is three months, could be worse. He will probably have surgery on Monday. A big blow for this weekend as he was in my thoughts. We needed his pace in the offensive side of the game. Not only for one game. If he is out for that long, several months, a big blow for us."

The bad news kept on coming at Colney with Josip Drmic and Timm Klose also out this weekend and Kenny McLean and Adam Idah major doubts.

"We still have just two centre backs," said Farke. "Timm Klose and Christoph Zimmermann are still out. Kenny McLean is a major doubt for this weekend. He got a knock on his back and was not able to train on Wednesday or Thursday. He did train on Friday but we have to see how he reacts.

"Adam Idah is another doubt. Same problem as Kenny. We have to wait and see how the body reacts to coming back to training on Friday.

"Josip Drmic is definitely out. He got a hamstring strain in training on Sunday. We think he will be out until after Chelsea.

"Some good news, though, Alex Tettey has been able to train with us and he is available for this weekend. Ibrahim Amadou had another full week with us and the same for Mario Vrancic."
