Kayode Odejayi went from hero to villain as AFC Wimbledon came from behind to grab a dramatic 1-1 draw and leave Accrington still searching for a first win of the season.
The veteran striker put Stanley ahead after 17 minutes as he rose highest to head home Lee Naylor's inswinging corner at the near post for his second goal of the season.
But on the stroke of half time the was shown the first red card of his career after raising his hands in the direction of Callum Kennedy.
From that point on the hosts dominated and in the second half Stanley's Marcus Bettinelli was called in to action to parry Jack Midson's close-range glancing effort, while Luke Moore was also denied by the keeper in the 76th minute.
But the pressure eventually told four minutes from the end when captain Alan Bennett rescued a point with a powerful header from Barry Fuller's cross.
