Griffiths joined Wolves on a two-and-a-half-year deal from Dundee in January 2011, but spent last season on loan at Hibs before returning in August until January.
The 22-year-old was rewarded for his 12-goal tally in the Clydesdale Bank Premier League with his first Scotland appearance in Luxembourg last night, but his club future is still to be determined.
Hibs boss Pat Fenlon hopes to retain Griffiths, defender Ryan McGivern and midfielder Jorge Claros, whose loan deals from Manchester City and Motagua in Honduras, respectively, end in the new year.
"I've stayed out of it. I've left that up to the chairman (Rod Petrie), that's his job," Fenlon said. "He's working away with Wolves and with Ryan McGivern at Man City and Jorge as well. It's a work in progress. We are trying very hard to keep the three boys. At this stage for us it will be extending them until the end of the season if we can."
Of Griffiths' Scotland call-up, Fenlon added: "I was delighted for him. He deserves it. He's worked really hard to get into that position."
