The Evening Times says the Celtic midfield maestro went to hospital yesterday to have his left knee examined after complaining of pain during Saturday's 3-0 win over Motherwell. Naka fears the original ligament damage, which occurred when he played against Spartak Moscow in August then flared up again in Donetsk on September 18, has not healed properly.

Now he has indicated he believes he will have to rest for another few weeks to allow him to make a full recovery.
