PRO unveils referee assignments for Week 4 (March 23-24)

Professional Referees Organization has announced the referees that will officiate the Major League Soccer matches this coming weekend.

U.S. born Matthew Foerster will be the center referee for Houston's match vs. Vancouver on Saturday at BBVA Compass Stadium. He will be joined in the field by assistant referees Paul Scott and Corey Parker and fourth official Hilario Grajeda.

Foerster has never been the center referee for a Dynamo match, but has served as the fourth official for Houston on two previous occasions. Foerster worked Houston's 1-1 draw vs. Sporting KC July 17, 2011 at Robertson Stadium as well as the second leg of Houston's 2012 Eastern Conference Championship series vs. D.C. United.
