Celtic striker Leigh Griffiths aims to be involved in the first team this week, manager Neil Lennon confirms.

The 29-year-old is hoping to make a return from injury after spending some time working his way back to full fitness.

Earlier this month the Hoops hero had been hit with a thigh strain and a virus and hasn’t appeared in Lennon’s side since their 3-1 win over Hearts back on August 25.

The Celtic gaffer 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.”

Striker Vakoun Bayo was seen limping during training at Lennoxtown as the team prepare to take on St Mirren tomorrow on a night of Premiership fixtures.

Speaking ahead of the match, Lennon said he has doubts about Bayo: “He took a knock yesterday so he is a major doubt for tomorrow.

"So we are a little bit short there with only one at the minute (Odsonne) Edouard, who is fully fit.

"Bayo is going for a scan today and we are hoping he should be okay for the weekend."

When asked, he said that he was ‘possibly’ looking to get a new striker in the January transfer window.

20-year-old Mikey Johnston is also hoping to make the first team by the end of the week after not playing for Lennon’s side since Celtic’s 2-0 win over Old Firm rivals Rangers.

There is some concern for the Celtic squad ahead of the Betfred cup semi-final against Hibs as other players sort other minor issues.

Tom Rogic has some inflammation again around his knee and Christopher Jullien seems to be fighting off a bug.

However, Olivier Ntcham looks set to return to Parkhead after being seen back in training and Ryan Christie is likely to come back onto the pitch after his two-match ban.
