American Mark Geiger has been selected to referee Wednesday's World Cup match between Portugal and Morocco.
Geiger becomes the second American to referee at two World Cups after David Socha in 1982 and 1986.
A 43-year-old from Beachwood, New Jersey, Geiger worked three games in Brazil four years ago, becoming the first American to referee a knockout stage match when he officiated France's 2-0 win over Nigeria in the round of 16.
Geiger was the Video Assistant Referee for last weekend's game between Argentina and Iceland.
