Timbers' tale: The Timbers are on a 12-match MLS unbeaten streak (14 counting two U.S. Open Cup wins). Midfielder Rodney Wallace is still away with Costa Rica's national team, but goalkeeper Donovan Ricketts and forward Ryan Johnson have returned from international duty. Portland's 24 goals leads MLS, as does its per-match average of 1.71. The Timbers have allowed 16 goals, giving them a goal differential of eight that ties Real Salt Lake for the best in MLS.
FC Dallas story: Blas Perez, who leads Dallas with five goals, is away on international duty. This is the first time former Timber Kenny Cooper has played a counting match in Portland since he was traded away to New York following the 2011 season. Cooper leads FCD in shots on goal (14). Cooper has three goals in league play, including the tying penalty kick in the May match between Portland and Dallas. He scored twice on Wednesday to help Dallas beat Houston in a U.S. Open Cup match. Midfield playmakers David Ferreira and Michel each have four assists.
Caleb Porter on Dallas: "They've been built the right way to win games in MLS." The Timbers coach listed individual skill, team chemistry and confidence, and set-piece efficiency as reasons for Dallas' success.
