SAO PAULO (AP) -- American referee Mark Geiger will work his first World Cup game when Colombia plays Greece on Saturday.
Kuipers is arguably Europe's top official and refereed the Brazil-Spain Confederations Cup final last June, and the Real Madrid-Atletico Madrid city derby at the Champions League final last month.
Geiger is a 39-year-old professional referee and former high school teacher from Beachwood, New Jersey.
The Colombia-Greece match in Belo Horizonte opens the Group C program.
