Joseph Mills fired Town in front but he was one of three men to depart the field with injury as Regan Poole's leveller was followed by two goals in the final 15 minutes to hand Dons the victory. Here's how we rate the Cobblers...
5. Michael Harriman
Pressed so high and hard he essentially played as a right-winger in the first-half. More defensive after the break... 6.5
6. Joseph Mills
Off the mark for Town in style. Fabulous technique to volley home after 13 minutes and he was having another good game until injury spoilt his evening. Hopefully not a bad one as he's going to be key this season... 7
7. Christopher Missilou
Town's pressing was a feature of the first-half and he was central to that but whilst he found himself in some advanced positions, the killer pass was lacking... 6
8. Ryan Watson
One glorious pass out to Harriman would have made for a terrific goal had the latter's cross found Smith. Mostly tidy, though did lose possession for MK's third... 6
