Cockfosters winning run came to an end as they suffered a 3-1 defeat against third place London Lions.
Lions began brightly and took the game to Cockfosters from the off and Josh Kennett caused problems for the hosts down the left flank.
Just as it looked like Cockfosters were settling into the contest, Kennett surged down the left, crossed into the box and Adam Bollie smashed a knock down into the roof of the net.
Cockfosters began to attack after going behind but the Lions defence, and keeper Mario Cenolli, held firm.
But in the 23rd minute the visitors failed to clear and Anton Lewis struck a rising effort beyond the reach of Cenolli. Cockfosters then pressed forward launching wave after wave of attacks but poor finishing, an unusual occurrence for the Reds, and the brilliance of Cenolli denied the hosts. The early second half continued with Cockfosters pressing forward, skipper Richard Morton blazed over and then Cenolli produced a fine double save to deny Butt and Protain.
Fosters were made to rue their missed chances as Lions retook the lead when a long ball found Daren Bern and he coolly rolled the ball home.
At the other end Bilal Butt tried to level matters up with a low drive, only for Cenolli to again deny the home side.
With time almost up and Cockfosters pressing men forward, Lions added a third.
The counter attack was always likely to lead to a chance and Bollie ran onto a ball over the top and calmly slotted home to seal the win.
Cockfosters have three cup matches before their next league game and will be looking to start another run of victories away at Corinthian Casuals in the London Senior Cup on Tuesday night before travelling to Oxhey Jets in the FA Carlsberg Vase next Saturday.
