Olympics 2012: Shocking Moments From the London Games
Michael Phelps Fails to Medal
Two-time returning champ Michael Phelps was dethroned in the 400-meter individual medley -- the most grueling race for swimming. Not only did he lose the gold to teammate Ryan Lochte, but the Olympian failed to even medal. After struggling in the preliminaries, landing in the eight and final spot in his heat, the U.S. swimmer placed fourth in the final.
