Match notes: The Timbers have some lineup uncertainty. Coach Caleb Porter on Friday said the availability of midfielder Diego Chara will be a game-time decision. Porter declined to comment on the status of left back Jorge Villafana or midfielder Michael Nanchoff. … Center back Nat Borchers begins his Timbers career against the team he played for the previous seven seasons. Borchers and midfielder Kyle Beckerman have played 10 seasons together (with Colorado and RSL). This will be the first time they have been MLS opponents. … Portland is 2-5-4 all time in regular-season matches against RSL, 1-1-3 at home. … This is the only time RSL visits Portland in the 2015 MLS regular season.
