Great Britain have added Jack Green and Nigel Levine to the team for the World Championships in Beijing later this month.
The pair were initially omitted, but after appealing to UK Athletics, the duo have been given the green light to compete.
Green will be part of the men's 4x400m relay and the 400m hurdles in China, while Levine will also compete in the 4x400m relay event.
The Championships will get underway on Saturday, August 22.
