NOT THEIR FINEST HOUR

The IOC is set to formally strip American cyclist Tyler Hamilton of his gold from the 2004 Athens Games and reassign the medals after his admission of doping, according to an Olympic official familiar with the case. After years of denials, and with the eight-year deadline approaching, the official told The Associated Press that the IOC executive board will meet Friday to adjust the standings from the road race time trial and award the gold to retired Russian rider Viatcheslav Ekimov. Hamilton told CBS's "60 Minutes" last year that he had repeatedly used performance-enhancing drugs.

PISTORIUS PROTEST

Double-amputee Oscar Pistorius and his South African teammates are moving on to Friday's 4x400-meter relay final without even finishing their heat. The man known as "Blade Runner" because of his carbon-fiber prosthetics will get a chance to run for an Olympic medal after officials accepted South Africa's protest over a collision between a Kenyan runner and South Africa's Ofentse Mogawane in the second leg of the race. Pistorius already is the first amputee to compete on a Summer Games track.
