American runner LaShawn Merritt will not compete in the 4x400-meter relay after being sent home from the Olympics to get treatment on an injured left hamstring.

In October 2009, LaShawn Merritt walked into a 7-Eleven a few minutes from his home in Suffolk, Va., after an evening at a nightclub. He paid cash for a box of condoms and had the clerk add a packet of four blue pills behind the counter called ExtenZe.

With water ponding on the track and the finish line in plain sight, 10,000-meter runner Galen Rupp waved to the crowd, smiled and stuck out his tongue.
