CHESTER are to appeal against the 56th minute dismissal of striker Mark Quayle - the first of two red cards as City moved to within one victory of a Conference promotion play-off spot.
Quayle was sent off for stamping on an opponent, but manager Mark Wright believes video evidence and promised support from the alleged victim will force referee Trevor Kettle to change his mind.
Defender Carl Ruffer followed Quayle off the pitch with 11 minutes left following his second yellow card leaving City to hold out with nine men.
It didn't prove that difficult as the Blues defence comfortably contained the Gravesend attack with the help of some solid goalkeeping from Wayne Brown who produced the save of the match after only four minutes from Tostao Kwashi.
Chester had one or two anxious moment in the first half, especially when Ben Davies had to head off his own line from Justin Skinner, but the deadlock was broken on 49 minutes.
Quayle set up the attack and Mark Beesley cut inside from the right before unleashing a low shot past goalkeeper Paul Wilkerson.
The referee's first red card of the afternoon was shown to Gravesend assistant manager Paul Handford who was sent from the touchline at the start of the second half for allegedly using foul and abusive language.
