Second half turnaround gives Accrington the win.
The result saw John McGreal's men slip to eighth in the table, but they remain only two points off the automatic spots as the League Two table starts to take shape.
At 1-0 up, the U's looked like they might be heading for another home victory, but Stanley turned it around in the second half.
Accrington Stanley produced a second half comeback to beat Colchester United 2-1 on Saturday, as the U's missed out on the chance to move up into the automatic spots.
The first half produced few chances for both sides as both midfields saw lots of the play. That was perhaps unsurprising when one of the league best attacks came up against one of the league best defences.
Sam Walker's long kick looked to be heading out for goal kick but Tarique Fosu managed to capitalise as the ball hit the corner flag.
It was patient play from Colchester as they kept the ball at the back waiting for an opening, Luke Prosser then clipped a ball into the chest of Chris Porter and his lay off was perfect for Wright to control and shoot to make it 1-0 to the U's.
Then, on the brink of half time, a free kick was flicked on by Kurtis Guthrie but went wide, as Colchester took that all important lead into the break.
Colchester came out quicker but couldn’t turn any of their forward momentum into goal scoring chances, although Chris Porter had a half chance cutting in on his left foot which was comfortably saved.
A Colchester attack broke down midway inside Stanley's half and Boco picked up the loose ball. He then travelled half the length of the pitch unchallenged and his goal bound strike took the smallest of touches off the inside of Lewis Kinsella's leg and into the U's net to make it 1-1.
John McGreal tried to change things by making substitutions, but they struggled to make the required impact as Colchester couldn’t break down a resolute Accrington defence.
