Mark Warburton has explained that Niko Krajncar will have a scan in the next eight to 10 days on his injury.

The Scottish Sun reported last week that the Rangers midfielder picked up a knee injury during training on Tuesday and there were concerns that he has serious ligament damage.

The report detailed that the 32-year-old collapsed in agony and was stretchered off the pitch in the bizarre training ground accident.

Rangers are yet to reveal the full extent of the injury but there are worries that he could miss the rest of the season.

Warburton has explained on Monday that Krajncar is set to see a specialist and will have to wait to determine the length of his layout.

“Niko had some inflammation on the knee. He will see a specialist for another scan in 8-10 days. Then we can see how he is,” Warburton said, as quoted by the club’s official Twitter account.

Rangers were without the experienced Kranjcar on Sunday, as they fell to a 1-0 defeat to Celtic in the Scottish League Cup semi-final.

Warburton was forced to use a midfield trio of Josh Windass, Andy Halliday and Jason Holt, but they struggled to match the quality of Celtic.

Kranjcar had recently settled in the Rangers side and made 15 appearances this season, scoring three goals and supplying three assists.

The Croatian moved to the Scottish giants this summer and joined with vast top-level experience after 15 years at the top for club and country.

He has previously played at English duo Tottenham and Portsmouth in the Premier League, as well Dinamo Zagreb, Hajduk Split, Rapid Vienna, Dynamo Kiev and most recently American side New York Cosmos.
