| The Ethiopian, who set a new 1500m world record 
				in 2015 of 3:50.07 before clinching the world title in Beijing, 
				was diagnosed with a partial rupture in her right foot after the 
				Zurich Diamond League meeting in August, Pineda Sport said in a 
				statement.
 The 28-year-old, who won silver at the 2016 Rio Games, is the 
				younger sister of triple Olympic gold medallist Tirunesh.
 
 Her withdrawal leaves Kenya’s defending champion and Olympic 
				gold medallist Faith Kipyegon and Ethiopian-born Dutchwoman 
				Sifan Hassan, who broke the world mile record (4:12.33) in July, 
				as favourites for the title.
 
 In another blow to the blue riband race at the global 
				competition, Kenya’s 1,500m defending champion Elijah Manangoi 
				announced earlier this week that he would not be defending his 
				title due to injury.
