The San Jose Earthquakes and Philadelphia Union played a game full of controversial cards, including a red card to Union left back Jordan Harvey, back on April 30. Despite going down a man, the Union managed to eek out a 1-0 win on the back of Amobi Okugo's penalty draw and Sebastien Le Toux's successful penalty kick conversion.
It was, however, Faryd Mondragon who received the most interesting caution: an unsporting behavior yellow card late in the first half. The Colombian goalkeeper got into a tiff with then San Jose defender Brandon McDonald over Mondragon's 50/50 challenge with Earthquakes star Chris Wondoloski inside the Philadelphia box. The two players went out one another, with Mondragon dwarfing McDonald during the argument.
