Rovers were beaten 2-0 by Northampton Town in Sky Bet League Two.
Danny Schofield's side found themselves behind less than two minutes in at the Eco-Power Stadium, as Mitch Pinnock's drive found its way through several bodies and into the back of the net.
Sam Hoskins then capitalised on an error from Jonathan Mitchell to score his 20th goal of the season and secure the win for the Cobblers.
