News broke today that Asbel Kiprop of Kenya allegedly failed an out-of-competition test for performance-enhancing drugs.

The 28-year-old 1500m specialist earned four global titles in his illustrious track career, including three world titles and the 2008 Olympic gold medal. 

Now, nearly a decade of track and field results could be tainted.

Below is a list of athletes who would move up into medal position if Kiprop were required to vacate all titles.
