Colchester United finished pre-season with a draw on Saturday afternoon, as a late Luke Norris penalty earned a share of the spoils.
The U's had conjured up plenty of chances through the game without being able to get back into the match after Dover had taken a first half lead.
But they kept at it, and some good work from Courtney Senior earned a penalty for Luke Norris to square it up.
It took eleven minutes for a real chance to be created and it fell to the home team, but Prosser was in the right place at the right time to block Effiong's low shot.
The U's followed up with two efforts of their own, but Hasanally's effort lacked power and Gambin's was off target as the visitors started to get into their groove.
The chances started to come, as Nouble was denied by a good stop from Mersin after Pell sent him away, before Dover were twice denied by Gerken seeing off efforts from Passley and Rigg, and Reason fired a shot just past the top of the post.
The U's thought they'd taken the lead on 36 minutes, but Pell's header was struck off by the offside flag. Nouble also had another effort, but Mersin again saved well.
The break in the deadlock came with two minutes to go, and with the U's down to ten men.
Vincent-Young was off receiving treatment for a head injury and the home side took full advantage, with Woods rifling home a loose ball from twelve yards out.
The U's trailed at the break, and Vincent-Young was replaced by James as the second half got underway.
And, with little happening in the first ten minutes of the second half, Gambin became the second player to be replaced as Senior came on in his place.
Hasanally had a big shout for a penalty not long afterwards as he was tripped in the box by Mersin, and saw his eventual shot saved despite fans and players alike calling for the spot kick.
Norris was next to go close for Col U, drilling in that forced a good stop out of Mersin.
And as the U's kept pressing, they eventually got themselves level with virtually the last kick of the game.
Courtney Senior showed some fine footwork to win a penalty in the final minute, and Norris made no mistake to tuck home, sending the keeper the wrong way.
