Paralympic Champion Bethany Firth has been forced to pull out of the British Team that will compete at the World Para Swimming Championships.
Firth has suffered from an ankle injury and will no longer be able to compete at the competition.
The world record holder will follow a rehabilitation plan supported by the British Para-Swimming Sport Science and Medicine staff and the Sports Institute Northern Ireland.
Firth said: “I am really upset that I won’t be able to compete at the World Championships in Mexico.
“I thought I might have had time to recover but the competition came too soon for me. I am working closely with the British Para-Swimming staff and Sports Institute Northern Ireland (SINI) to get back to my best for next year.
“The World Championships will still be an amazing competition and I want to wish my team-mates the best of luck over there. I know they will be amazing.”
National Performance Director Chris Furber added: "I know that Bethany is disappointed to miss the World Championships but the time frame for recovery meant that she was not able to be ready for Mexico.
“Our medical team is working closely with SINI to ensure that she is following the best rehabilitation plan possible to ensure that her 2017/18 season runs smoothly.”
