The clubs were due to meet at Parkhead last night, but Celtic announced on Tuesday that the fixture was off amid the grounding of many flights across western Europe due to an ash cloud emanating from the Icelandic volcano.
All British airports were reopened on Tuesday night and the game has therefore been given the go-ahead for Wednesday, with a 7.45pm kick-of.
Entry is free for season book holders, while non-season book holders can purchase tickets priced at 10 for adult and 3 for children.
Meantime, Josh Thompson is coming to terms with the highs and lows of being a Celtic defender. The 19-year-old was signed from Stockport by Tony Mowbray last summer with a view to the future.
However, Thompson has been a regular since the turn of the year due to injuries to Glenn Loovens, Jos Hooiveld and Thomas Rogne, and picked up Celtic's Young Player of the Year Award on Sunday night.
"This season has been more than I expected," Thomson said. "I never expected to play nearly as much as I have. But I'm more than happy to be playing, even in games that haven't gone our way. I just want to be involved. I feel I've improved a lot since I came in."
