Korea and Mexico will aim to secure World Cup knockout berths when they meet in Guadalajara on Thursday.
Korea and Mexico head into the fixture at Estadio Akron after victories over the Czech Republic and South Africa last week. A win would guarantee a last-32 berth.
Son Heung-min is one goal away from becoming Korea's all-time World Cup leading scorer with four. He is tied with Ahn Jung-hwan and Park Ji-sung and is set to start against Mexico.
Coach Hong Myung-bo made one change from the lineup against Czechia, with Kim Moon-hwan replacing Lee Tae-seok. Mexico will be without Cesar Montes, who was sent off against South Africa.
Hong Myung-bo described a drone spotted over the training ground as "unfortunate" but insisted it "did not impact us significantly."
