One night after Usain Bolt electrified the crowd at Olympic Stadium with his second straight gold medal in the men's 100 meters, the track and field competition continues Monday with five medal events on tap.
The men will compete for gold in a pair of one-lap races: the 400 meters and 400m hurdles.
The United States won gold, silver and bronze in the 400 four years ago in Beijing, but won't take even one medal in the event here in London because the Americans failed to qualify a single runner for the final. Not counting the boycotted 1980 Moscow Games, the last time the U.S. failed to win a medal in the 400 was in 1920.
LaShawn Merritt, who won the 400 for the U.S. in Beijing, was expected to be a medal favorite again, but didn't finish his semifinal race after pulling up lame with a hamstring injury. Lalonde Gordon of Trinidad and Tobago is one of the favorites to win gold in the 400 after posting the fastest time in Sunday's semifinals.
The U.S. will have three participants in the 400 hurdles and Angelo Taylor figures to have the best shot at gold. Americans Kerron Clement and Michael Tinsley are also capable of making the podium.
The women will also compete in medal events Monday in the pole vault, shot put and 3,000-meter steeplechase. Yelena Isinbayeva is the world-record holder and heavy favorite to win the pole vault. She is going for her third straight gold in London.
The U.S. women's soccer team, chasing the country's third straight Olympic gold medal, will play Canada on Monday at Old Trafford with a berth in the final on the line. The winner of the match will play either France or Japan on Thursday. Those teams also play Monday at Wembley Stadium.
USA's Gabby Douglas has had a few days to soak in her women's all-around gold medal. She takes aim at more hardware on Monday in the uneven bars final.
Douglas is up against a deep field and qualified sixth in this event. She'll look to crack a talented top three that includes Great Britain's Elizabeth Tweddle -- the top qualifier with a score of 16.133 -- China's He Kexin and Russia's Victoria Komova, the runner-up to Douglas in the all-around.
For the men, they'll participate in apparatus finals on the rings and vault.
Chen Yibing of China was the top qualifier and he'll look to repeat his gold- winning performance from the 2008 Beijing Games. He'll go up against the likes of Matteo Morandi of Italy, Russia's Aleksandr Balandin and 39-year-old Iordan Iovtchev of Bulgaria, the oldest male gymnast competing at the London Games.
On the vault, top qualifier Denis Ablyazin of Russia will try to hold off reigning world champ Yang Hak Seon of South Korea and Enrique Tomas Gonzalez Sepulveda, who is aiming to become Chile's first Olympic gymnastics medalist.
Men's basketball will have its final day of preliminary action and the matchup between the U.S. and Argentina will decide the winner of Group A. Both teams have already clinched a spot in the quarterfinals.
Also, Lithuania and Nigeria both have a chance at landing the tournament's final quarterfinal berth. Lithuania will earn the spot with a win over Tunisia, while Nigeria need a win over France and help from the Tunisians.
In track cycling, medals will be awarded in the men's sprint, with the semifinals and gold medal race on tape. Great Britain's Jason Kenny and France's Gregory Bauge, who has won three of the last four world titles, have a chance to meet in the final.
Additionally, Victoria Pendleton will aim to reach the semifinals of the women's sprint. The British rider, who has already won a gold medal in the keirin, and Australian Anna Meares are the favorites as quarterfinal heats take place. The women's omnium, a two-day, six-event competition new to the Olympic program, kicks off. Sarah Hammer is the United States' entry.
Medals will be awarded in the women's Laser Radial and men's Laser classes. Australia's Tom Slingsby is in position to win the Laser, while there is a tight race in the Laser Radial. Four sailors are separated by one point.
The men's 470 and 49er, as well as the women's Elliott 6m match racing event, will also be in competition.
Greco-Roman wrestling medals will be decided in the men's 60kg, 84kg and 120kg categories.
The shooting program at the London Games come to a close with medals being handed out in the men's 50-meter rifle three positions and the men's trap event.
Trap qualification began on Sunday and Australia's Michael Diamond scored a perfect 75. Five shooters, including world No. 2 Italian Massimo Fabbrizi, scored a 74. Qualifications will conclude on Monday before the final.
American Matthew Emmons is looking to win gold in the other shooting event after a disappointing fourth finish in the 50m rifle 3 positions in 2008.
Weightlifting medals will be handed out in the men's 105-kilogram class while the team jumping competition wraps up Monday in equestrian.
