Switzerland defender Michel Morganella has been expelled from the Olympics for directing an allegedly racist insult at South Koreans on Twitter.
The Swiss Olympic delegation has sent the 23-year-old home after he posted the message in the wake of the team's 2-1 defeat to South Korea on Sunday.
"Michel Morganella gravely insulted and discriminated against the South Korean people and their football team with his highly offensive comments," said Gian Gilli, the Swiss chef de mission. The player has apologised. He said: "I wish to apologise to the people in South Korea and their team, but also to the Swiss delegation and Swiss football in general."
