The game hinged on the sending off, which led to the penalty from which Lee Trundle hit the winning goal in a 2-1 win for the Swans.
But the FA Disciplinary panel met on Tuesday and agreed to rescind the card. Iron reserve striker Andy Parton will stay on at Stalybridge Celtic until the end of the season.
The 21-year-old initially joined Celtic for a month on February 7, but has made a big impact at the Conference North side, prompting manager John Reed to extend his loan.
