Doncaster Rovers missed the chance to climb into the top half of the League One table as they went down to a 1-0 defeat to Oxford United at the Keepmoat Stadium.
James Henry scored the only goal of the game for Oxford just past the hour mark as the visitors eased their relegation worries with the three points.
Doncaster suffered their first home league defeat since October as manager Darren Ferguson freshened up the squad.
Doncaster made five changes to their side for the clash against Oxford with Craig Alcock, Mathieu Baudry, Luke McCullough, Rodney Kongolo and Alfie May all coming into the starting eleven.
Oxford had the best chance to open the scoring in the first half but Mathieu Baudry denied striker Jonathan Obika’s with a clearance off the line.
The home side had their best chance of the first half when Alfie May was denied by Oxford goalkeeper Simon Eastwood after he had cut-through the Oxford defence.
Doncaster started the second half brightly and John Marquis saw his diving header go just wide.
Matty Blair then forced Eastwood into a good save after he had found space at the far post.
Doncaster were made to pay for the misses soon afterwards when Oxford substitute Henry saw his diving header beat Marko Marosi in the Doncaster goal.
Marquis had the best chance to equalise for Doncaster but his effort was tipped over by Eastwood as Doncaster lost for the first time in seven games.
