Northampton and AFC Wimbledon shared the spoils at Sixfields in a game that visiting boss Neal Ardley called 'a really good advert for League Two' after Lyle Taylor's equaliser for his side.
Chris Wilder's side take another point towards promotion and with Plymouth suffering a surprise defeat at Barnet it means the Cobblers are 11 points clear of both the Pilgrims and Oxford United.
Those two sides meet at the weekend while Northampton make the long journey to face Carlisle United.
Outside of the promotion places, Accrington Stanley were also beaten and that means Town have a 19-point gap to 4th place.
