Manager Nigel Pearson believes the FA must take action against the quality of refereeing in the Championship after suggesting his side were denied a penalty and claiming there was offside in the build-up to West Brom's last-gasp equaliser.
City were seconds away from heading into the international break with three big points when Andi Weimann brilliantly volleyed home Rob Atkinson's header in the 83rd minute to score his 18th goal of the season.
But the Baggies salvaged a point when substitute Adam Reach finished off a smart team move although Pearson believes Jake Livermore was offside during the play.
