(Matthew Kitchen, NBC Olympics) Day one of competition brought some controversy when the North Korean women's soccer team refused to come out of their locker room for more than an hour before their match in Glasgow Wednesday. 

Apparently someone on the stadium staff attached a graphic of the South Korean flag to the North Korean team's player photos during introductions prior to their game against Colombia.

“We’re sorry for the delay. We have problems backstage,” was the announcement from the stadium staff as the stall wore on. The match was supposed to begin at 7:45 p.m. local time, but didn't begin until 8:50 p.m. Organizers apologized for the mistake.
