Having won four out of their last five, the Gills have put themselves within two points of the play-offs, albeit having played more games than most of the side around them.
Meanwhile, Andy Butler's Doncaster will need to resolve a three match winless run if they want to keep their place in the play-off places. They currently sit in fifth position.
Steve Evans will have the benefit of his side facing no fresh injury concerns going into the match. Gillingham will most likely field an unchanged lineup as a result.
Doncaster will be bolstered by the return of four players who had been kept out by injury in recent games. Reece James, Josh Sims, Omar Bogle and former Gills loanee Scott Robertson will all be available for selection. Additionally, AJ Greaves has also been passed as fit after a knock saw him go off in the midweek defeat to Oxford United.
Jon Taylor and John Bostock remain absentees for the Yorkshire side.
Gillingham (4-4-2): Bonham - Jackson, Cundy, Tucker, Ogilvie - Graham, Dempsey, O'Keefe, MacDonald - Oliver, Akinde.
Doncaster (4-2-3-1): Jones - Halliday, Wright, Anderson, James - Smith, Greaves - Sims, Richards, Coppinger - Okenabirhie.
The Gills are in great form going into this match, having won four of their last five. Defeat to Fleetwood Town has been the only blip in recent weeks, but a confident 3-0 display away to Lincoln City reaffirmed that the Kent side are there to challenge for an outside chance at a play-off spot.
It's also impressive to note they've managed to score three times in each of their last four victories, proving the attacking side of their game is very effective.
Scoring no goals in that period may also be seen as a concern, but Omar Bogle's return to the squad may help ease that worry.
Ones to watch
Vadaine Oliver will undoubtedly be the one to watch for Gillingham. The striker is having the best goalscoring season of his career having notched 15 in all competitions so far. He's also impressively managed seven in his last seven matches, so he'll be one the Rovers defence will have to keep an eye on.
James Coppinger may be the one to watch for Doncaster. The veteran midfielder is still proving he has much to offer, and demonstrated his ability by setting up both goals in the 2-1 win over Plymouth Argyle last month.
The 40-year-old is retiring at the end of the season, so he'll be doing his best to help his side gain promotion this campaign.
The two sides last met in the reverse fixture this season back in February, where Doncaster ran out 2-1 winners at the Keepmoat Stadium. Kyle Dempsey initially cancelled out Reece James' opening goal, but Brad Halliday's effort just two minutes later saw the points go the way of Rovers.
In the overall head-to-head record it's the Gills who lead the way though, with 34 wins compared to Donny's 14. There have also been 19 occasions where the points have been shared.
