RIO DE JANEIRO — FIFA has replaced the Colombian assistant referee whose offside decisions denied Mexico two potential goals against Cameroon.

FIFA says Humberto Clavijo will not be in referee Wilmar Roldan’s team for South Korea vs. Algeria in Porto Alegre on Sunday.

Clavijo will be replaced by Christian Lescano of Ecuador, according to FIFA’s website.

In other Sunday assignments, FIFA picked Nestor Pitana of Argentina to referee United States vs. Portugal in Manaus.

After beating Ghana 2-1, the Americans could advance from Group G with a second win.

Pitana previously handled a 1-1 draw between Russia and South Korea in Group H.

Felix Brych of Germany will referee Belgium vs. Russia at the Maracana Stadium in Rio de Janeiro.

Brych’s first match was Costa Rica’s 3-1 win over Uruguay.
