Leyton Orient came from behind to reach the second round of the FA Trophy with a 2-1 victory at Haringey Borough.

An early Michael Ademiluyi strike gave the hosts hope of an upset, but after trailing at the break Josh Coulson got Justin Edinburgh’s men back on terms with a 58th-minute volley.

The O’s completed the turnaround with 11 minutes to go when Matt Harrold headed home with his first touch after coming off the bench.

Having started the 4-1 victory over Sutton United, Harrold dropped to the bench as David Mooney returned to the stating XI, while the fit-again Coulson made his first appearance since late September in place of Dan Happe.

In front of record attendance of 1,133 at Coles Park, it was the hosts who were celebrating in the fifth minute when Ademiluyi broke free and fired a low shot past Dean Brill.

Macauley Bonne had chances to get the O’s back on terms, while Mooney also headed a James Dayton cross wide, before the midfielder saw a great opportunity parried by Ashley Harris.

Despite the pressure from Edinburgh’s men, Haringey went close to doubling their lead after 34 minutes when Brill superbly got down to his left to keep out Anthony McDonald’s effort.

Following the restart, the O’s continued to up the pressure and their efforts were rewarded in the 58th minute when Jobi McAnuff whipped a corner towards the far post where Coulson fired in his first goal for the club via the woodwork.

Coulson was immediately replaced by Happe in a like-for-like change, before the visitors set about finding the winner.

After Craig Clay had seen a low effort tipped wide by Harris, the midfielder saw a superb curling effort beat the Haringey keeper, only to see the ball crash back off the post.

But after Edinburgh had brought on Harrold to replace Alex Lawless with just over 10 minutes remaining, the change was to immediately reap dividends as the striker headed in a McAnufff corner.

Brill needed to make a couple of late saves as the hosts adopted a more direct approach in search of an equaliser, but the O’s were to see out the late pressure to get through.
