Today's Fab Five, which will highlight NBC's prime-time schedule starting at 8 pm Eastern:
1. Men's 200m Butterfly
Another night, another shot at history for Phelps, who will be going for his third straight gold medal in this event. No Ryan Lochte in this one, so all eyes will be on Phelps as he chases career gold medal No. 15 and attempts to tie Russian gymnast Larisa Latynina's record of 18 career Olympic medals.
2. Men's 800m Freestyle Relay
Provided Phelps is able to medal in the 200m butterfly, this race takes on added significance, as it represents Phelps' chance to become the most decorated Olympian of all time. A medal in the 200 and 800 relay would give the Olympic legend a staggering 19 career medals.
3. Women's Gymnastics Team Finals
The men fell flat, so it's up to the American women to salvage U.S. pride and find their way to the medal stand. Jordyn Wieber will have to shake off the crushing disappointment of failing to make the individual all around finals and the American women to their first all-around gold since the Magnificent 7 in 1996. That's a heavy weight for a 5-2, 117-pounder to carry, but she's up to the task.
4. Men's and Women's Tennis
Novak Djokovic will face American Andy Roddick, and Maria Sharapova takes on Laura Robson of Great Britain to highlight the tennis slate.
5. Men's Basketball
The 2012 edition of the Dream Team should barely break a sweat against Tunisia, giving coach Mike Krzyzewski a chance to experiment with different lineup combinations.
