The Cobblers hopes of capturing an automatic promotion place were dented this afternoon against relegation candidates York City.
Before an expectant crowd of 6,608, Northampton failed to put the visitors under pressure and conceded goals on 7 and 85 minutes.
They are in sixth place with a game in hand on those teams around them and must put today's defeat behind them as they prepare for Tuesday nights visit to Adams Park to play Wycombe Wanderers.
