The Celtic striker had been doing extra training ahead of Saturday’s encounter at Celtic Park.
Leigh Griffiths may be a doubt for Celtic’s visit of Hibernian on Saturday.
That is after the Scottish Sun reported the striker was absent from Celtic’s Friday morning training session.
Griffiths controversially withdrew from Scotland’s squad earlier this month to build up his fitness.
And according to Chris Davies, the Celtic number two, he had been doing extra training in order to achieve that.
But the insinuation now is that Griffiths may have over-exerted himself ahead of the Celtic Park encounter with his former club.
Celtic can climb above second-placed Hibs with a win and could even return to the top of the table if Hearts are beaten by Aberdeen.
Odsonne Edouard will be expected to keep his place in Celtic’s attack should Griffiths miss out against Neil Lennon’s side.
How big a blow would losing Griffiths be to Celtic’s chances against Hibernian?
