Huddersfield Town's winless streak has been extended to eight games after the club were denied a rare win by a last-minute strike from Blackpool forward Nathan Delfouneso.
Anthony Gerrard headed Huddersfield ahead from Adam Clayton's deep outswinging corner on 66 minutes.
It was Gerrard's first goal for Town and it came from the Terriers' only attempt on target.
Blackpool dominated proceedings for most of the match, bossing possession with over 60% and registering no fewer than 14 shots at goal.
Huddersfield keeper Alex Smithies was in fine form, producing impressive saves to deny Isaiah Osbourne and Thomas Ince.
Blackpool's forwards were also guilty of wasteful finishing though, as Ince, Alex Baptiste, Gary Taylor-Fletcher and Wesley Thomas all spurned good chances to score.
However, the visitors got the goal that their play deserved in the third minute of time added on, as Delfouneso tapped home from close range following a run from Ince.
