Celtic striker Leigh Griffiths to take time out of football

Celtic boss Brendan Rodgers has revealed that Leigh Griffiths will be out of football "for a period of time" as he "needs some help."

The Hoops striker, recently returned from illness and another calf injury, came off the bench in the 5-1 Ladbroke Premiership win over Kilmarnock at the weekend but missed training on Wednesday morning and is out of Celtic's Europa League Group B clash with Salzburg at Parkhead on Thursday night.
