Note 1: Match originally played on August 24, 2011 (kickoff 20:00), but abandoned at halftime due to lightning, heavy rain, and a tornado warning (FC Dallas was leading 1–0 on a goal by Jackson Gonçalves in the 18th minute). Replayed the next day restarting at 0–0 as tournament regulations required unfinished games be replayed completely.[5]
