University of East London 1st conceded late on as they drew 2-2 with Imperial University 1st at Beckton District Park.
Imperial took the lead with a quick fire second half goal but a Stefan Wright header levelled things up shortly after.
UEL gained the lead with just four minutes left as Johan Caney-Bryan slotted home for his 15th goal in eight matches.
An injury-time goal by Imperial spoiled the party for UEL but remain top of the league and unbeaten this season in all competitions.
UEL dominated the early exchanges as the Imperial keeper gave UEL a free-kick after he handled the ball out of his area, Stefan Neilson stepped up but his shot was well held by the keeper.
Dillan Stephenson lifted a great arrowed cross to the far post for an unmarked Shahid Kasako which caused an instinctive reflect save from the keeper.
Kasako kept the ball in play and worked the ball back to Stephenson who ran on to the layoff which fizzed narrowly wide.
Imperial had their first dangerous attack 18 minutes in as the striker found space on the left and his low shot was denied by a fingertip save by Dan Robinson.
The hosts had the majority of possession and played most of the first half in the visitors half but lacked the final pass and cutting edge, as it stayed goalless at the break.
UEL were caught off guard with the defence on the back foot. Imperial scored virtually from the restart as a ball was lifted over the top of the defence and the striker lifted the ball over Robinson to lead.
The goal sparked UEL to live and responded three minutes later as a corner taken by Saio Levi-Blackwood, whipped in at the near post for Wright to power the header down into the bottom corner.
Imperial almost regained the lead minutes later after a corner was not dealt with by UEL and a snap shot on the penalty spot went over.
Stephenson went on a darting run and shrugged of two defenders before getting a shot off and forced a good save down to the keepers’ right at the near post.
UEL grabbed the lead four minutes from time after great work down the left flank, Darren Hammond at the by-line cut it back for Caney-Bryan to slot home in the bottom corner.
East London just had to close out the final minutes but in the 92nd minute the ball was only half cleared, for the Imperial striker to run on to and his shot crept agonisingly past Robinson to equalise.
