Carter swam a time of 23.67 seconds to finish behind South Africa's Chad Le Clos in a time of 23.37 seconds.

A report in the UK Guardian says that George Bovell III is bowing out of international competition and has lashed out at the international swimming federation, FINA, for not cracking down on doping within the sport.
The Guardian's article was published just after 4pm Thursday and the Guardian says Bovell spoke to the newspaper after placing 3rd in his Rio Olympic heat Thursday.
George Bovell swam 22.30 to place 3rd in the 50 metres freestyle preliminaries in Rio.
However, his time was not enough to get him into the semi-finals tonight.
Only the swimmers with the top 16 times go through.
Bovell swam in lane 7 in Heat 8 at 12.16 Thursday afternoon.
