Burundi's Francine Niyonsaba will miss the World Championships in Eugene, Oregon after failing to recover from a stress fracture in time for the competition, where she was set to participate in the 5,000m and 10,000m events.
"Me and my team we did everything possible to recover," Niyonsaba wrote on Instagram on Monday. "I am almost OK now but I couldn't train for all this period, so I'm not in the shape ... to perform the way I wanted."
