Hendon extended their unbeaten run to 18 games in all competitions and 14 in the league despite being reduced to ten men in the first half.
The final score was 2-2 against play off hopefuls Dulwich Hamlet, but the game was goalless when James Fisher was sent off in the 37th minute.
The first goal came in the 49th minute when Xavier Vidal gave Dulwich the lead, but fifteen minutes later, Sam Murphy netted from the penalty spot to equalise, his 4th goal in 4 games.
Dave Diedhiou put the Greens ahead with ten minutes to go, but the visitors secured a point when Jordan Hibbert equalised in the final minute of normal time.
Hendon's title hopes now hang by a thread with Maidstone United winning 2-1 against Grays Athletic - the Greens are 6 points behind with a game in hand, but the hold on 2nd place has been strengthened as Margate lost 1-0 at Leatherhead.
Focus now turns to the League Cup final against Grays on Wednesday night at Whyteleafe.
