The 31-year old criticized officials on his site whilst watching his team play against the Seattle Sounders.
Ching was selected for the US national team for the CONCACAF Gold Cup so wasn’t playing for his club, but was able to watch from home.
After a decision from linesman Emiliano Monje, Ching tweeted the following:
"Ref in Seattle just cheated the Dynamo. What a joke.
"Not even close. Ref is a cheat."
Ching later posted two apologies but MLS decided to fine him $USD500.
