The one issue that has plagued Major League Soccer during the first five weeks of the season has been the enforcement of red cards.
In the 42 matches played across the league since March 6, 16 ejections have been delivered by 13 different referees.
The concern about the presumed growing number of red cards throughout the United States and Canada came to the forefront again after four players were sent off during Week 5.
During a conference call with the media on Thursday afternoon, Professional Referees Organization general manager Peter Walton tried to clear things up regarding the increased criticism of officials.
