Just after the 30-minute mark Scunthorpe drew level when Harry Bunn fired home via a deflection. The United comeback was complete six minutes before the break as they were awarded a penalty of their own which Ryan Loft converted.
After coming on as a substitute on Saturday, Aaron could well make his Sky Bet League One debut on Saturday 7 August when The Dons travel to Doncaster Rovers in their first match of the 2021/22 season.
As for Ellery Balcombe, he was an unused substitute as Burton Albion were beaten 2-0 at home by Newcastle United in pre-season.
The Magpies found the net in each half with Jacob Murphy and Joelinton earning Newcastle the win on the day. A Burton XI will face Belper Town on Tuesday before Albion get their League One campaign under way with a trip to Shrewsbury next weekend.
