The Surrey-based official will travel to the Cherry Reds Record Stadium for his tenth game of the campaign and his fourth in Sky Bet League One.
His first game of the campaign was a 2-2 draw between Stevenage and Tranmere Rovers in which he showed two yellow cards and one red - the dismissal coming for two cautions to Johnny Hunt of the home team.
He's taken charge of the Iron on five occasions in total, most recently in January when the side drew 1-1 with Portsmouth at Fratton Park where he issued four cautions. He's only made one visit to Glanford Park, back in October 2013. In those five games, he showed a total of 20 yellows and no reds.
Meanwhile, he's refereed AFC Wimbledon on nine occasions - their most recent being a slender 1-0 defeat to Fleetwood Town back in March. Three red cards have been shown across the fixtures. Saturday will be his seventh competitive trip to referee at Kingsmeadow.
In 2017-18, he took charge of 47 games, issuing 163 yellow cards and eighteen red. So far in this campaign, he has officiated in nine encounters, showing 25 yellows and five red.
On Saturday, Breakspear will be assisted by Stuart Butler and Matthew Smith, while Nicholas Cooper has been appointed as the fourth official.
