A TERRIBLE performance saw Concord lose their first match in 11 games as Lewes stuffed them 6-3 at home.
Horrific errors destroyed Concord, who came up against opponents who played with a high tempo.
Disaster struck inside 15 seconds as the hosts lost the ball deep into their own half, allowing Nathan Crabb to run into the box and make it 1-0.
Just as a shell-shocked Concord appeared to settle down, the visitors struck again as centre back Jack Lampe tried to jink his way out of a tight spot and was tackled before Ben Godfrey hit a shot past Tom Lovelock.
The hosts appeared to be back in the game when Tony Stokes curled the ball into the top left hand corner of the goal in the 33rd minute.
But Harry Elmes' error - as he failed to clear a free kick - saw Lewes take a 3-1 lead in the 37th minute as the ball bounced to Chris Breach, who scored.
Beachboys manager Dan Cowley used all three subs at half time and his side did seem more upbeat.
But a fantastic goal in the 66th minute killed them off when right back Jon Dollery struck an outside-of-the-boot shot about 35 yards out on the right wing which curled into the net - leaving everyone stunned.
In the 72nd minute Lampe fired home a shot at the back post to give Concord some hope, but Crabb scored again six minutes later after Breach nodded back in Jamie Strong's cleared corner.
Crabb completed his hat-trick in the last minute with a penalty after debutant Abou Diarra was pulled back in the area by Ade Osifuwa.
Stokes grabbed a consolation goal in the fourth minute of extra time, but Concord finished knowing they had performed awfully, a point their boss made clear.
Cowley said: "From the first minute everything went wrong. Every single goal from our point of view is avoidable and we got to swallow and learn from that.
"It was a kamikaze performance and we had absolutely no control at all because ultimately we didn't have players doing the right thing at the right time."
