Bristol City have contacted the Professional Game Match Officials Board (PGMOL) following another game in which the Robins were denied what they believe to be a clear penalty kick.
Sky Sports News have reported that the club have contacted Championship referees manager Kevin Friend - coincidentally a City fan - to request an investigation into the continuing trend which has seen the Robins go 430 days without a spot-kick being awarded in their favour.
Bristol Live understands there has been no formal request to Friend or the PGMOL to conduct such an investigation, but in their post-match report, which is filed after every game, City have asked for clarification as to why two first-half incidents against Swansea City in Sunday's FA Cup tie went unpunished.
