Sean O'Driscoll's Doncaster recorded their third successive goalless draw.
In the early stages the match showed promise, with Blackpool's Shaun Barker cracking a 20-yard shot on to the bar.
A minute later Barker was in action at the other end, clearing Paul Green's cross off the line - but thereafter the game fizzled out as a spectacle.
Blackpool had a chance to win three minutes from time following a blunder by Sean Thornton, but Keigan Parker fired wide with only Jan Budtz to beat.
