Allyson Felix beaten by diving Shaunae Miller in Olympics 400m final

Allyson Felix was denied a fifth Olympic gold Monday after being edged out in dramatic fashion by Shaunae Miller of the Bahamas in a thrilling women's 400-meter final at Rio 2016.

Miller, who led going into the final straight, dived over the line to beat the world champion into second place, while Jamaica's Shericka Jackson came third.

Miller's dive stirred some controversy on social media, though some prominent names in track and field came to her defense.

"Shaunae Miller's dive was to recover from falling. Sprinters know the quickest way across the line is a well timed lean. Trust me on that," former Olympian Michael Johnson tweeted.
