The Robins took a two-goal lead with two penalties, the first converted by John Melligan and the second by John Finnigan with 11 minutes left.

But a minute later Marcus Richardson headed past Scott Brown after a cross from Tom Curtis.

And Drummond then struck his dramatic equaliser, scoring from eight yards after a cross from Carl Regan.

Cheltenham's first penalty was awarded for a handball by David Artell and the second for a handball by Ben Davies.

Prior to the first decision Chester keeper Stephane Gillet had pulled off a fine double save to deny Gavin Caines and Kayode Odejayi.

Drummond's late strike sparked wild scenes of jubilation from the 800 visiting fans.

But with six minutes of injury-time played Cheltenham almost snatched a dramatic winner, Brian Wilson's shot flying narrowly over the crossbar.
