Coventry Ref 'Naive'

The official was criticised for allowing Kevin Blackwell into his dressing room at half-time during the game at the Ricoh Arena on March 18.

The Sky Blues complained about the Championship official to the Professional Game Match Officials (PGMO) which selects referees for the Premiership and Football League, and Oliver has subsequently been warned.

PGMO referees manager Jim Ashworth admitted Oliver's actions were 'naive and illconsidered' and he has been made aware that they were not only contrary to the agreement but that he had inflamed the situation.
