Two delays because of lightning in the area -- one before kickoff and one in the first half -- saw the contest shortened to 80 minutes.

Frustratingly, another round of electrical storms brought proceedings to a halt, with players exiting the field and the near sellout crowd of 78,128 at the iconic home of the NFL's Green Bay Packers instructed to seek shelter in the concourses.

The disruptions didn't dampen the festive atmosphere for the first professional soccer match ever held at Lambeau, with a few hardy fans even braving the pounding rain and risk of lighting to remain in their seats during the stoppage.
