American runner Abbey D’Agostino will not compete in Friday’s 5,000m Olympic final after tearing her anterior cruciate knee ligament.
D’Agostino, 24, collided with New Zealand’s Nikki Hamblin during qualifying in Rio on Tuesday, with both then trying to help each other finish.
Both completed the race and were put through to the final, but D’Agostino left the arena in a wheelchair.
Her injuries will rule her out of the rest of the season.
“By far the best part of my experience of the Olympics has been the community it creates and what the Games symbolises,” D’Agostino said.
