The Portland Timbers had experienced good results against their traditional USL rivals since going to Major League Soccer in 2011, especially on the road.  In 2011, they drew 1-1 with their traditional rival Seattle at Qwest Field, then beat their other USL rival Vancouver 1-0 at the opening of BC Place.

But that run of good results would come to a crashing halt when they faced the third of their traditional USL rivals, the Montreal Impact, as the Timbers fell 2-0 on two late goals, the first a penalty kick by Bernardo Corradi in the 76th minute, and eight minutes later on a goal by Sinisa Ubiparipovic.

The Timbers also lost goalkeeper Troy Perkins, who left with an injury not long before the first Montreal penalty kick when Montreal forward Sanna Nyassi (who once played for the Timbers in an exhibition match against Morelia) had his cleats expose as he lunged for a ball and cut Perkins across the nose. The Timbers keeper had to leave the match, with Joe Bendik seeing his first Timbers MLS action for the final 27 minutes, giving up the two goals in the process.
