When Portland Timbers fans saw that the team had been drawn against rivals Seattle Sounders FC in the fourth round of the 2015 Lamar Hunt U.S. Open Cup, there was some trepidation among fans given the previous year's USOC meeting, a match the Sounders won 3-1 in extra time.
Like that match, the 2015 contest would once again be played at the Starfire Sports Complex in Tukwila, Wash.
The match started harmlessly enough, as both teams played to a scoreless draw at the end of one half of play.
However, after Diego Valeri scored the game's first goal in the 48th minute, and as the Sounders frantically pushed forward for the equalizer, the drama quickly accelerated.
