Rachael Kelly requires swimoff for World Championships semi-final qualification

Great Britain swimmer Rachael Kelly will take part in a one-on-one race in an attempt to qualify for the semi-finals of the 100m butterfly at the Swimming World Championships.

Kelly completed her heat in joint-16th, level with Egypt's Farida Osman in 58.48 seconds.

With just 16 places available in the semi-finals, only one of the swimmers can go through, and they will race against each other this afternoon.

Great Britain's Jemma Lowe narrowly missed out on a place in the semi-final after finishing 19th in a time of 58.74s, while Sweden's Sarah Sjostrom set the pace with 56.47s.
