Tommy Rowe's piledriver secured a vital point at Blackpool which strengthened Rovers' play-off push.
Rowe smashed home a leveller with 15 minutes to go at Bloomfield Road which moved Rovers a point ahead of seventh-placed Peterborough in the battle for a top-six finish.
Rovers made four changes to the starting line-up, with Rowe, Ali Crawford, Kieran Sadlier and Alfie May coming back into the side.
The home side made two changes of their own, bringing Donervon Daniels, Jordan Thompson and Chris Long into their starting XI.
The match opened in a scrappy style, as may have been expected with a muddy pitch plus wind and rain creating tough conditions.
Rowe had Rovers' first opportunity when he worked space inside the area after six minutes, only for his effort to be deflected by.
Rovers had to work hard for opportunities, but enjoyed some success through Danny Andrew down the left - with a cross finding May, who scooped an effort wide, and a shot from the left-back running through to Crawford whose first-time effort was just wide.
The game was beginning to open up and Crawford had a shot from distance after 22 minutes which was too close to home keeper Mark Howard to cause him any real problems.
The Seasiders' first real effort came after 27 minutes when Liam Feeney sent the ball wide from a diving header. There were further efforts from Gnanduillet twice going close and Jordan Thompson firing straight at Marko Marosi.
The last chance of the half went to Rovers, with Crawford played through by Rowe before the Scottish midfielder cut inside onto his left foot for a shot which was well held by Howard.
The home side took the lead four minutes after the restart when Michael Nottingham stabbed the ball home after a corner was not cleared fully by Rovers.
Rovers fought back, with Ben Whiteman curling an effort just wide after 56 minutes.
Manager Grant McCann used all three substitutions available to him in a quick period, sending on Tyler Smith to replace May before James Coppinger and Herbie Kane came on to replace Sadlier and Whiteman.
Coppinger had an immediate influence by using his skill to find space in the area before laying the ball off for Rowe to smash home the equaliser.
And Crawford could have nicked a win for Rovers with a last-gasp free-kick, but Howard was well placed to hold his well hit free-kick.
