NC State alum Cullen Jones is competing in three swimming events in the 2012 London Olympics: the 50m Freestyle, 100m Freestyle, and the 4x100m Freestyle Relay. The relay event is the one in which Jones won gold in 2008. That relay team also set a world record.
Below is his 2012 schedule in chronological order. The start times listed--I assume--do not correspond to television coverage times since NBC is tape delaying a bunch of stuff as usual. They couldn't be bothered to show Ryan Lochte vs. Michael Phelps in the 400m IM live on Saturday, so it's tough to say when these events will actually hit the airwaves. You should be able to watch them live online, though.
