The Celtic head coach and striker have been discussing the 32-year-old midfielder.
Celtic were well beaten in Norway during their Europa League clash and Commons expressed his frustration when he was substituted during the second half.
He unleashed a verbal tirade aimed towards assistant manager John Collins and likely boss Deila, too.
But Griffiths says it is important the 32-year-old has now apologised and that the Celtic side as a whole will move on.

LG: It has been dealt with now and he’s apologised so it’s forgotten about and we look forward to Sunday. (MD)— Celtic Football Club (@celticfc) October 23, 2015
LG: He has come in and apologised to the boys so we leave it there and focus on the weekend. (MD)— Celtic Football Club (@celticfc) October 23, 2015
Deila himself also reacted positively to Commons' response and is keen for the Bhoys to move past the episode.

Have Celtic simply swept this one under the carpet? And has the incident taken the pressure off the coaching staff after a poor result and even worse performance on another big European night?
The Scottish champions will have to bounce back and they can't afford any more games like the 3-1 defeat in Molde.
Celtic host Dundee United during their next Scottish Premiership clash on Sunday afternoon. Deila will want a response. But the fans will want one even more.
