Reports this afternoon have suggested that Kim Collins has been withdrawn from the Olympic Games by his nation St Kitts and Nevis.
It is believed that the sprinter has been punished for refusing to stay in the same accommodation as his teammates, choosing instead to stay with his wife.
The 36-year-old has also fuelled speculation further with a succession of tweets.
"My fans. I won't lie. Won't be running later tonight @LO2012," he wrote on Twitter. "For those who saw me run in Mexico. That's the last time I represent my country.
"Even men in prison get their wives to visit."
Collins has previously represented his country at four Games.
