Rangers' Niko Kranjcar ruled out for six months with cruciate ligament injury

Rangers midfielder Niko Kranjcar has been ruled out for six months with a cruciate ligament injury.

Manager Mark Warburton confirmed the news on Wednesday, revealing that the Croat is likely to miss the rest of the season.

Kranjcar suffered the problem in training a fortnight ago and has travelled to London to undergo surgery.

"Niko is unfortunately suffering from an ACL injury," Warburton told reporters in a press conference. "He's currently having it reconstructed by one of the best surgeons down in London.

"It will be a six-month rehabilitation period for Niko. Everyone in the building is so disappointed for him. They know how hard he works."

As a result of the injury blow, Warburton has claimed that he may consider bringing in a replacement on loan in the January transfer window in order to boost the squad's "strength and depth".

The former Tottenham Hotspur midfielder joined Rangers from New York Cosmos in June.
