It was Jaakko's second outing for The Dons ahead of the new season, and first start. Ilias Chair and Lyndon Dykes gave the hosts a two-goal early lead which was extended after the break as Paul Osew netted an own-goal. Jaakko was withdrawn with 15 minutes to play as Glyn Hodges' side suffered a first defeat ahead of the new campaign.
Luka Racic wasn't involved as Northampton Town beat Leyton Orient 1-0 in their first pre-season outing. Sam Hoskins early goal proved decisive against the League Two side at Sixfields. Next up for The Cobblers is a game against Championship side Luton Town on Saturday.
