Rangers ace Niko Kranjcar will undergo knee surgery on Wednesday that is set to keep him out of action for six months, following a training ground accident, according to a report.

The Daily Record reports that the 32-year-old midfielder had his worst fears confirmed by a specialist on Tuesday, with the Croatian almost certain to miss the rest of the season.

Kranjcar will now go under the knife in London on Wednesday, with his season set to come to a crushing end due to cruciate ligament damage.

The former Premier League player joined the Glasgow giants in the summer following his move from New York Cosmos.

He made 15 appearances in all competitions for Mark Warburton’s side, scoring three goals and supplying the same number of assists.

The former FA Cup winner was beginning to find his feet at Ibrox, but the training ground accident has now brought his season to a devastating end.

The news will be a big blow for his club manager Warburton, who has now lost two summer signings for different reasons, with Joey Barton’s career at Ibrox seemingly at an end.
