The 24-year-old opened the scoring for the Bhoys on Saturday afternoon.
To start with, Celtic's top scorer last season put himself right in the frame, winning a penalty and dispatching it within minutes against Ross County.
However, a subsequent injury may have cast doubt as to whether the 24-year-old is the man to start for the Bhoys in place of Nadir Ciftci in Azerbaijan.
Even if Griffiths' injury wasn't serious, Ronny Deila would have to go for his sharpest forward for such a crucial clash.
But, after the game, assessment of the injury revealed it wasn't bad enough to rule Griffiths out in any way and a delighted Celtic striker reacted on Twitter to his side's win.
Good result today. 3 points, a goal, and a clean sheet. We go to Wednesday now and try get through the tie. pic.twitter.com/LJ8qG8IJLp— leigh griffiths (@Leighgriff09) August 1, 2015
He also confirmed that his fitness issues aren't serious and that he is fit for selection against Qarabag. Griffiths' pace could make him the perfect man to lead the line in the second leg.
Injury isn't serious and I hope to be fit for selection on wednesday. @celticfc— leigh griffiths (@Leighgriff09) August 1, 2015
Stefan Johansen doubled Celtic's lead against County as they got off to a smooth start to their Scottish Premiership campaign. Can anyone realistically stop the Bhoys?
