Oscar Estupinan ended his goal drought to earn Hull a share of the spoils against 10-man Blackpool.
The Seasiders went ahead when Sonny Carey seized on a defensive error to score for the first time this season.
But the visitors had to play most of the second half a player short after Jordan Thorniley was shown a straight red card for hauling down Estupinan.
The Colombian striker salvaged a point by heading in Louie Coyle's cross for his first goal in nine games.
The draw lifts Blackpool to 22nd place in the Championship, two points behind Hull.
