Carlisle's Richie Foran and Huddersfield's Steve Yates were both sent off at half time in the tunnel after a bad-tempered first 45 minutes exploded on the whistle.
Striker Foran had fought a running battle with the impressive Terriers' back line but was forced to watch the second half of his side's 2-1 defeat from the stands.
Steve Yates also saw red to add to Huddersfield's already poor disciplinary record this season.
On the pitch, the home side were much superior, a 2-1 scoreline flattered Carlisle.
It could easily have been a cricket score had it not been for the heroics of Carlisle's goalkeeper Matt Glennon.
As early as the third minute he made a trio of incredible reaction saves in just seconds as Town Captain Andy Booth rattled quick fire shots at his goal.
But Town's break through was deserved when Booth scored midway through the half. A shot from Schofield hit Booth, who quickly reacted and fired high into the net.
The now rampant Terriers piled on the pressure and Carlisle could hardly get the ball.
The home side doubled their lead when in-form 20-year-old striker Jon Stead hooked a wonderful shot past Glennon from the edge of the box.
The players emerged from the break in sombre mood rocked by the sendings off and the game settled down.
Carlisle, sensing Huddersfield had taken their foot off the gas, began to press on and the game's balance shifted.
The Cumbrians grabbed a goal in the closing stages meaning Huddersfield, who should have been home and dry, were left clinging on.
A floated corner beat a crowded six-yard box and Darren Kelly flung a leg at the loose ball.
It was the first goal the Terriers had conceded in more than eight hours of football at the McAlpine Stadium.
Carlisle could sniff a point and Huddersfield were certainly on the back foot.
Both Shaun Smith and Craig Farrell rasped close range shots they really should have scored against the crossbar in the dying seconds.
But the visitors could not find the equaliser and they have now lost their last seven games on the bounce leaving them rock bottom in Division Three.
Huddersfield Town manager Peter Jackson said although his side dominated they could have lost it at the death.
"We could have been six up in the first half and then lost 3-2 in the second. It was a no win situation for us because we were expected to take all three points from the game." Paul Simpson, who claims he was on the toilet when the half time brawl broke out said: "I think the sendings off affected Huddersfield Town more than us because we came out in the second half and put in a strong performance. We shot ourselves in the foot with mistakes in the first half."
