Most notably, of course, was the departure of manager Darren Moore, who left his post with the club to take on a new role with Sheffield Wednesday.
Rovers are still very much in with a fighting chance of mounting a promotion charge, however.
But where do the experts think Doncaster will finish now that Moore has left, and who are they tipping for promotion to the Championship?
One set of data analysts have released their latest predictions on how the League One table will finish - and it makes for interesting reading after a busy period in the division, which has seen a number of teams drop points.
Scroll down and click through the pages as we see where their unique formula is predicting Rovers to finish come the end of the 2020/21 campaign:
1. 24th - Bristol Rovers
The Gas lost to Swindon Town in midweek to further compound their relegation woes, and aren't being tipped to pull up any trees in the final months of the campaign. They recently sacked Paul Tisdale (above), so can new appointment Joey Barton secure survival? The experts don't think so. Predicted points total: 42 Photo: Dan Mullan
2. 23rd - Rochdale
A side who have taken points from the Black Cats this term, Brian Barry-Murphy's side are being tipped to finish in the bottom four after some shaky results in recent weeks. Predicted points total: 43 Photo: Justin Setterfield
3. 22nd - Wigan Athletic
Even after a points deduction, the experts were still tipping Wigan to stay up for much of the season but now believe they won't be able to retain their League One status - despite a Bahraini takeover lifting the mood. Predicted points total: 44 Photo: Alex Livesey
4. 20th - AFC Wimbledon
The Dons dismissed manager Glyn Hodges as they look to climb away from relegation danger. And the experts believe that move will pay off - with Wimbledon narrowly tipped to avoid the drop. Predicted points total: 44 Photo: Justin Setterfield
