Cotterill Far From Happy With Referee.
City boss Steve Cotterill was not happy with the defeat as he insisted that his side should have been given a certain penalty early in the second half.
Midfielder Luke Freeman was clearly brought down in the box by Uwe Hunemeier but referee Iain Williamson reached for his cards and showed Freeman a yellow for diving instead of pointing to the spot.
The decision cost the Robins dear, the side looked comfortable after Derrick Williams had given them the lead, but former City man Sam Baldock levelled matters with a tap in after the break.
Zamora then gave Frank Fielding no chance with a left foot shot, the goal that won it for the home side.
But after the game, Cotterill was fuming at the decision not to award City a penalty.
He told BBC Sport: 'It was a nailed-on penalty and to book the player made it worse. The yellow card was an insult.
'Luke Freeman is not experienced enough to look for a dive. It is not in his thoughts and it beggars belief really.'
The Robins now sit in 21st place in the table with 10 points from 12 games.
