MK Dons slipped to a 2-1 trip away at automatic promotion chasers Doncaster Rovers.
The Dons had never previously won at Doncaster and their aim of changing that got off to a bad start when Joe Ironside put the home side ahead after a defensive error.
Scott Hogan equalised for the visitors, only for Rob Street to win the game for the hosts, handing Doncaster a fourth straight win in League Two to move up to second and reduce the gap to league leaders Walsall to seven points.
As for MK Dons, defeat means they have won just one of their last six games, with the latest result seeing them sit in 11th position in the table and nine points off the play-offs.
A reshuffled Dons team took to the field in South Yorkshire, with Craig MacGillivray and Nathan Thompson absent through injury, leading to starts for Tom McGill in goal and new signing Jack Sanders in a back four.
The visitors had a few early opportunities, with home goalkeeper Ted Sharman-Lowe making stops to deny Alex Gilbey and Hogan.
But after a generally even start, Doncaster would take the lead just after the half-hour. A rushed pass by Sanders to Jay Williams lead to Ironside pinching the ball off the latter, before placing a strike into the bottom corner.
Doncaster saw Jamie Sterry miss the target when well placed just after the break as the hosts tried to continue to build up an advantage.
MK Dons came close when Callum Hendry headed just wide, but just before the hour mark, the Dons would equalise just before the hour mark. Space opened up down the Dons’ right hand side for Gilbey, who fed Hogan to score.
In response to losing their lead, Doncaster had the chances to try and go back in front, with McGill making saves to keep out Patrick Kelly and Luke Molyneux.
The hosts would take the lead for a second time in the 73rd minute. Jay McGrath’s pass released substitute Street, who held off Nico Lawrence before firing across and beyond McGill.
MK Dons had possession in response but couldn’t find a way through, as they were beaten at Doncaster.
The team will seek to go again when they host fellow mid-table outfit Bromley next time out in their only home game in February.
