Quigley had finished third in 9:40 just behind Gesa Krause of Germany and Hyvin Kiyeng Jepkemoi of Kenya, the defending world champion. She edged out Kenya's Purity Cherotich Kirui, who is now listed as the final auto qualifier from the first heat.
"[There were] a couple Kenyans up front just blocking everybody," Quigley said immediately after the race of the slow early pace . "It ended up being a 400m steeplechase race which is kind of fun! It's fun to steeple when you're running fast. I knew I had a good last 400m so I felt good about that."
A few minutes later, her status in the official results was switched from 'Qualified' to 'Disqualified."
At 1:47 PM CT, USATF tweeted that the disqualification will stand. Lewis Johnson of NBC reported on the live feed that USATF officials watched the video replay and did not file an official protest as it was obvious Quigley had stepped on the line.

Americans Emma Coburn and Courtney Frerichs both advanced to the final automatically by placing second and third in their respective heats.
After her race in heat three, U.S. champion and Olympic bronze medalist Coburn said that the athletes were not allowed to watch the prior heats from the call room so she was running "blind" in regards to pace needed to make the final. She also seemed unaware of Quigley's disqualification.
"I was just guessing," she said.
