Trailing to Myles Peart-Harris’ goal on the half-hour, capitalising on a rare Jamie Cumming mistake, Eisa struck first just before half-time before netting the winner six minutes after the restart.
Defensively, Dons restricted the hosts to scant few chances despite their late pressure as they climbed to 19th in the standings, out of the bottom four for the first time since early October.
Here’s how we rated the players.

. Jamie Cumming - 6.5
Not a lot to do in terms of facing chances, but will have to take responsibility for Rovers' goal after it looked like he spilled the ball to allow Peart-Harris to score. Photo: BEN STANSALL
. Top Don: Jack Tucker
Won everything thrown in his direction. Made big headers late on when Rovers piled pressure on, and limited the home side to skant little. Photo: Pete Norton
. Zak Jules - 7.5
Like Tucker, looked excellent in the closing stages and held firm. Photo: BEN STANSALL
. Daniel Harvie - 7.5
The pantomime villain. Won free kicks in important areas, disrupted play and caused a general nuisance. His best outing in weeks. Photo: BEN STANSALL
. Tennai Watson - 7
Limited chances down his flank, and held his own when shifted inside to centre back in the closing stages when Dons switched to a back three. Photo: Clive Mason
9. Jonathan Leko - 6.5
A decent debut. Tried to do a bit too much at times on his own, but once he got his head up, picked out Mo Eisa for the equaliser just before half time. Faded in the second half before coming off on the hour. Photo: Jane Russell
10. Mo Eisa - 7.5
Two more vital goals to his name. Ran channels in the first half before switching to a more central role in the second. Could have had a hat trick but Devoy's pass was just out of his reach Photo: BEN STANSALL
11. Will Grigg - 6
Covered a lot of ground for no reward. Couple of half chances but little else to write home about Photo: Pete Norton
12. Sub: Conor Grant - 6
With Dons playing with their backs to the wall, did a decent job trying to clear the lines Photo: Jane Russell
