Here are five things to look out for at the London Olympics on Thursday:
---
1. USAIN BOLT: The Jamaican sprinter runs in the men's 200-meter final. If he wins, he'll be the first Olympian to repeat the so-called sprint double of 100-meter and 200-meter golds.
2. WOMEN'S SOCCER: The United States plays Japan at Wembley in a repeat of last year's World Cup final.
3. ONE MORE CHANCE: South Africa has won an appeal to advance to the 4x400-meter relay final despite a crash in the heat. That means Oscar Pistorius, a double-amputee runner, can compete for a medal on Friday.
4. DOPING: The IOC is set to formally strip U.S. cyclist Tyler Hamilton of his gold from the 2004 Athens Games and reassign the medals after his admission of doping.
5. WOMEN'S BOXING: The first Olympic gold will be awarded, with American Claressa Shields slugging it out with Russia's Nadezda Torlopov.
