Nine-man Boston United saw their FA Cup dream crushed by Altrincham following a controversial fourth qualifying round tie at the Jakemans Stadium.
After a bright start, the Pilgrims took the lead in the 11th minute when striker Mark Jones scored for the fourth consecutive game.
But the contest was turned on his head a minute later when Ben Fairclough was sent off for a rash challenge.
Boston bravely held out until the 58th minute when James Lawrie scored following a fine move.
The home side were then reduced to nine men when Spencer Weir-Daley saw red following an off-the-ball incident.
With United two men down, there looked to be only one winner and Altrincham duly took control. Jake Moult gave his side the lead when his 20-yard drive took a massive deflection and beat keeper Dan Haystead.
The Pilgrims almost levelled when substitute Charley Sanders' curling shot, following a goalmouth scramble, dropped inches wide.
But the visitors secured their place in the first round proper when Nicky Clee drove home a minute from time.
