Adam Gemili will not compete in August's World Championships in Beijing after pulling out on medical advice.
Gemili is the reigning European 200m champion but suffered a hamstring tear whilst racing at the Birmingham Grand Prix in June.
In the same race Gemili was however able to beat his personal best, breaking 10 seconds for the very first time, making history as the first Briton to run sub 10 seconds in the 100m, and sub 20 in the 200m.

The 21-year-old has been advised it would be "too big a risk" to compete in Beijing, by British Athletics performance director Neil Black, after making a steady recovery at Team GB’s holding camp in Fukuoka, Japan.
Although he was not selected to compete in an individual event, Gemili was scheduled to race in the 4x100m relay.
"He has made amazing progress and it is a reflection on him that he so wanted to fulfil his commitment to the relay programme," said Black. However, we have to make difficult calls occasionally and this is the best for him with the Rio Olympics and the London 2017 World Championships on the horizon."
Gemili was openly disappointed but understood the decision of the team.
"I'm disappointed that I can't be part of the team, but I do understand the decision. As the performance director Neil has to make those sort of calls and I respect that he has done so, even though he knew I wanted to carry on.
"It will be very hard to watch from the sidelines in Beijing, but I will do anything I can to support the rest of the guys in their final preparations for the championships."
