Next month's World Athletics Championships have suffered another star withdrawal, following no-shows for Kenya's Olympic 800 metres champion and world record-holder David Rudisha, and American sprint star Tyson Gay.
Reigning 100 metre world champ Yohan Blake now also isn't competing - the 23-year-old Jamaican won't be defending his title thanks to a hamstring injury.
Rudisha pulled out of the Moscow event with injury, while Gay's gone for returning a positive drugs test, rather than injury.
