London 2012 Olympics: Day 14 must-see moments

British taekwondo hope Sarah Stevenson could cap a traumatic 18 months with an Olympic medal, while BMX star Shanaze Reade and Britain's 470 sailors have gold in their sights.

Full schedule available on BBC Sport website

World champion Stevenson was one of the stories of the Games four years ago when she won bronze after a scoring error was overturned. In the last 18 months she has lost both her parents to terminal illness, won the world title and overcome a serious knee injury.

Muhammad will want to prove his controversial selection ahead of world number one Aaron Cook was merited, after a protracted wrangle with the governing body. If successful, Stevenson and Muhammad will take part in preliminary (09:00), quarter-final (15:00), semi-final (17:00) and final (22:15) rounds.

Reade gets her chance to make up for the disappointment of crashing in Beijing after qualifying fifth fastest for the semi-finals (15:00), with the final at 16:30. Caroline Buchanan of Australia was the fastest qualifier.

Fellow Briton Liam Phillips was impressive in making quick progress to the semis (15:08) and also harbours hopes of a medal in the men's final (16:40). Dutchman Raymon van der Biezen won all his qualifying heats.

Patience and Bithell are guaranteed silver and hope to overhaul Australia's Mathew Belcher and Malcolm Page for gold in the medal race (12:00), which was postponed on Thursday because of light winds. That sets up a potential day of double gold for Britain's sailors, with Saskia Clark and Hannah Mills going into the medal race (13:00) of the women's 470 level at the top of the standings with New Zealand's Jo Aleh and Olivia Powrie.

Britain has a healthy representation of two finalists in the women's 1500m (20:55). Dobriskey, who considered quitting the sport earlier this year due to potentially fatal blood clots on her lungs, qualified fourth in her semi-final; Weightman, coached by BBC Sport commentator and former Olympic silver medallist Steve Cram, went through as one of the two fastest losers.

The women's 5,000m final (20:05) will see a fascinating clash between Ethiopia's Tirunesh Dibaba and Kenyan Vivian Cheruiyot. Steve Lewis goes in the pole vault (19:00) and Sophie Hitchon in the hammer final (19:35), the relays continue with the finals of the women's 4x100m (20:40) and the men's 4x400m (21:20), and the Jamaicans are expected to star in the first round of the men's 4x100m (19:45).

  • BOXING (14:00-22:56): GB men

Four British men have the chance to guarantee at least silver medals as the semi-finals take place at the ExCel. Bantamweight Luke Campbell faces Japan's Satoshi Shimizu (14:00), welterweight Fred Evans is up against Ukraine's Taras Shelestyuk (21:30), middleweight Anthony Ogogo takes on Esquiva Falcao Florentino of Brazil (15:00), and super-heavyweight Anthony Joshua meets Ivan Dychko of Kazakhstan (22:30).

  • DIVING (19:00-22:45): Tom Daley , 10m platform

After missing out on a medal in the synchronised event with partner Pete Waterfield, Daley will get his campaign for individual success underway in the preliminary rounds of the 10m platform (19:00). The semi-finals and finals take place on Saturday.

Great Britain's women had high hopes of contesting the gold medal match but Argentina's semi-final win means it is they who will take on the Netherlands in the final (20:00). Britain must raise themselves to play New Zealand for bronze, which would equal the best-ever performance of Barcelona 1992.

The United States will not take their men's semi-final lightly as they face Argentina, the side who beat them on the way to a shock gold in Athens eight years ago, at the North Greenwich Arena (21:00). Spain face Russia in the other semi-final (17:00).
