Kieran Dowell has had successful surgery on his Rangers injury.

The midfielder, 26, has been ruled out for a lengthy period after picking up a knock during the winter break.

And Philippe Clement has revealed Dowell has had surgery to correct the issue he suffered during the warm-weather break to La Manga.

The Ibrox boss previously explained that Dowell was dealt the cruel injury blow after his studs caught in the pitch in training.

"Kieran was really unlucky that he stuck in the grass on a bad pitch," said Clement. "He will be out quite a long time normally."

Now, Dowell has come through surgery with Clement stating the operation "went well". 

However, Rangers will be without Ben Davies, Kemar Roofe and Danilo. Abdallah Sima is also sidelined after injury ended his time at the Africa Cup of Nations with Senegal.

Clement said today: "Ben is still not available.

"Kieran Dowell had his operation, everything went well. That is positive also that the operation went well.

"Kemar and Danilo are also still out.

"It is short term [for Ben Davies] but the other guys are longer term, Abda also. Ben is more shorter term. I cannot put a timescale on that."

On Sima, he added: "That is things to discuss if we have a good assessment about the injury and what to do.

"That is why I want to give the information when I have it and not too early.

"Of course from the first moment when we were contacted we directly contacted Brighton. We are working together in that way."
