The young forward had agreed to a short loan spell with the Championship club on September 16, and made his debut just a day later against Watford.
And he had looked as though he was rediscovering the form that created such a hype when he began his Old Trafford career, after scoring three goals in five appearances for Paul Dickov’s side.
However, Macheda was forced to limp out in the 75th minute of Doncaster’s 1-0 win over Leicester at the weekend, and has since returned to his parent club for treatment.
However, Doncaster manager Paul Dickov has expressed his desire to bring the 22-year-old back to the Keepmoat Stadium once his injury has cleared up.
“He came off with a tight hamstring and will be missing for a good few weeks but we are still looking at extending his deal as we hope to have him back soon,” Dickov told the club’s official website.
“We are speaking to Manchester United to do a deal to get him back once he is fit.”
Macheda has struggled for form and fitness since he burst onto the scene as a teenager in 2009, and scored a crucial last minute winner against Aston Villa which proved pivotal as United won the Premier League title ahead of arch rivals Liverpool.
The goal earned him cult hero status at Old Trafford, but he has struggled to find the net at his parent club and during various loan spells since.
