Chivas USA at Portland Timbers on Saturday Chivas USA will look to overcome their scoring troubles Saturday against Portland. Victor Decolongon / Getty Images / March 11, 2012 April 6, 2012, 4:38 p.m. When: 7:30. Where: Jeld-Wen Field, Portland, Ore. Records: Chivas 1-3, Portland 1-2-1. Record vs. Portland (2011): 1-1. Update: Chivas USA, which has scored just one goal in four matches, will be without its most dynamic offensive threat for the fourth straight week: Forward Juan Pablo Angel was again ruled out with post-concussion symptoms. Also remaining on the sidelines is midfielder Michael Lahoud, who hasn't played this season because of a right hamstring strain. But even without them, this could be the game that snaps short-handed Chivas out of its scoring slump because Portland has allowed more goals, six, than all but two teams in the Western Conference. At the other end of the field, Chivas keeper Dan Kennedy is third in the MLS with 16 saves; yet he has just one win - and three 1-0 losses - to show for it.
