Switzerland's Olympic football team has expelled defender Michel Morgan-ella from the tournament for posting racist comments on Twitter.
An offensive message aimed at South Korean people was posted from his Twitter account after Switzerland lost 2-1 to the Koreans on Sunday.
The account has since been deleted and he has apologised.
Meanwhile, teenager Ruta Meelu-tite won Lithuania's first ever Olympic gold in the pool by beating American Rebecca Soni in the women's 100m breaststroke.
The 15-year-old, who goes to the same Plymouth school as Tom Daley, led from the start and beat the fast-finishing Soni by 0.08 seconds.
