10 years later, American Lashinda Demus poised to win Olympic gold after Russian hurdler stripped of medal for doping

Russian 400-meter hurdler Natalya Antyukh will lose her gold medal from the 2012 London Games due to doping, putting American Lashinda Demus in position to be named the champion more than a decade after the race.

The Athletics Integrity Unit, which oversees doping cases in track and field, announced Wednesday that Antyukh had not appealed a penalty handed down two months ago that included the stripping of her results from July 2012 through June 2013. The AIU said the IOC could now "proceed with the reallocation of medals and the update of the IOC database."

Zuzana Hejnová of the Czech Republic and Kaliese Spencer of Jamaica are in line to receive silver and bronze.
