The men's quarterfinals will wrap up this afternoon in London, as the light flyweights, light welterweights, and light heavyweights take to the ring to set up their medal round matchups at the 2012 Olympics. We'll have live updates for each fight, starting at 3:30 p.m. EDT.
CNBC won't have coverage until their tape delayed fights this afternoon, but NBCOlympics.com will have almost-live streaming for all the fights.
Top three fights/reasons to watch this afternoon:
1. (Light Flyweight) Paddy Barnes (Ireland) vs Devendro Singh (India) - Singh already pulled off one big upset, knocking off Mongolia's Pürevdorj Serdamba in the round of 16. Can he take down another favored, seeded competitor?
2. (Light Heavyweight) Julio la Cruz (Cuba) vs Yamaguchi Falcao (Brazil) - This has been, along with heavyweight, the weakest division so far. But unlike the heavies, light heavy does have a true standout fighter in the Cuban.
3. (Light Welterweight) Tom Stalker (Great Britain) vs Munkh-Erdene Uranchimeg (Mongolia) - First off, Uranchimeg can fight. Second, Stalker wasn't particularly impressive in his win over Manoj Kumar, which some felt was a gift for the Brit.
