Rovers suffered their first league defeat of the season as late sucker punch from Armaud Gnanduillet in injury time sealed a 1-0 win for visitors Blackpool at the Keepmoat Stadium.
After a scrappy but balanced opening 45 minutes, Rovers had most the second half's best chances. Niall Ennis had one cleared off the line and both Ben Whiteman and Jon Taylor forced good saves from Seasiders stopper Jan Alnwick. However, in the dying seconds Rovers were hit on the break and substitute Gnanduillet was there to head past Ian Lawlor.
