Gary Hooper has returned to the Celtic squad for the second leg of their Champions League qualifier against Cliftonville on Tuesday night.
The 25-year-old, who has recently been linked with a move away from the club, missed last week's 3-0 win in Ireland with a groin strain.
Queens Park Rangers and Hull City are reported to be leading the race to sign the forward.
Celtic will reach the third qualifying round of the competition if they see off Cliftonville at Parkhead.
