Despite Rian Bray's 25th minute red card, the Beavers almost held off the Clarets of Chelmsford City, but a late penalty awarded by the assistant allowed Rhys Murphy to equalise for the visitors.
Dan Bowry came back into the starting eleven for the Beavers and after a quiet and cagey start, Chelmsford created the first chance as Tom Wraight headed the ball over the bar.
Both sides had a number of half chances but it took until the 20th minute for a really clear one; Chelmsford keeper Nathan McDonald's weak clearance fell to Chris Dickson, but his attempt was neither a cross or a shot and drifted wide.
Lovelock had to punch away a Chelmsford corner after the Beavers had been caught on the break down the right hand side, but after that the game changed.
A second challenge by Rian Bray appeared to catch the referee's eye and after an early yellow card, the referee showed him another and he had to go off, leaving the Beavers a man light.
The Beavers almost had their opener on the half hour as Zak Joseph managed to find himself a bit of room in the D and his shot struck the post and rebounded away.
Chelmsford couldn't take advantage of their superiority as the Beavers readjusted and defended stoutly, but the task was not helped by Oli Sprague having to go off with what looked like a hamstring injury, Nathan Mavila slotting in, a like for like substitution.
Hampton looked to be going in at halftime holding on to the goalless scoreline with some comfort, but in added time, CHRIS DICKSON showed why the Beavers signed him. A pass from the right found him between two Chelmsford defenders, but holding them off, he hit a screaming shot past McDonald that beat the keeper all ends up and left him dumbfounded.
The second half was mostly Chelmsford, although Hampton nearly had a second as Michael Corcoran's header hit the post, as the visitors had a lot of possession and pressure without them creating many clear chances. What chances they did create were right at Tom Lovelock, as everyone put in a great shift in defence of the points.
With 10 minutes left, the Clarets created their best chance as substitute Shaun Batt managed to break through and face Tom Lovelock in a one on one; it looked for all the world like the striker would score but Lovelock came out and made himself big, blocking the shot just inside the box.
Hampton looked like they would hold on for the points but they were undone by what looked like a contentious decision in the 89th minute.
A cross into the box hit Simon Downer and went out for a corner, but the assistant then flagged for what turned out to be a handball, which wasn't too clear by any means. After the furore of the Hampton protests had settled down, Rhys Murphy stepped up to score from 12 yards and deny the Beavers the 3 points.
