The Celtic hitman is set to return to full training in a couple of days.
In short, Celtic need another striker to rival Odsonne Edouard.
Neil Lennon's side are scoring goals for fun right now, but there'll be a patch when they're in short supply and the Northern Irish manager will need an alternative to Edouard.
After all, Rangers, who sit behind Celtic on goal difference in the Premiership, have Alfredo Morelos and Jermain Defoe, both of whom are scoring on the regular for Steven Gerrard this season.
In contrast, Lennon has had to make do with only Edouard for the most part, but that's about to change shortly.
The Scottish marksman has been sidelined since August with a thigh problem and then a virus, but Lennon confirmed his imminent return.
He said: "Leigh is back on the grass now. He has been doing some physical work with the fitness coaches and we hope he starts training again on Thursday.”
This is a major boost for Celtic. After all, we're talking about a player who scored 40 goals for the Bhoys during the 2015-16 campaign.
When he's on it, few can match Griffiths as a goalscorer and Lennon will be delighted with the extra option up front.
