MLS ref replaced after photo in Miami jersey

Referee Guiherme Ceretta was replaced by Jaime Herrera for the fixture by the Professional Referees Organization (PRO). A spokesman for PRO confirmed to ESPN that "Referee Guiherme Ceretta was removed from the game due to a potential conflict."
The Miami jersey has become the biggest selling shirt in MLS after Lionel Messi joined the club in July. Messi was in the starting lineup for Saturday's Florida derby against Orlando. MLS's regular referees are currently locked out by PRO after talks broke down over a new collective contract.
The Professional Soccer Referees Association (PSRA) rejected an offer from PRO and the league began last month with replacement referees from outside the PSRA's ranks.
