Michael Phelps will have a chance to break the Olympic record for individual medals Tuesday.
Phelps, who already owns the record for individual gold medals -- 14 total, breaking American Mark Spitz's old record -- will swim in the 200 meter butterfly, followed by the 4x200 freestyle.
The 200 meter butterfly will be at 7:49 p.m. London time (2:49 p.m. Eastern) and the 4x200 freestyle will be at 8:51 p.m. London time (3:51 p.m. Eastern). If Phelps, a former Michigan Wolverine, medals in both of those, the all-time medal mark will be his.
Also of note: Team USA will play its second game of the London Olympics at 6:15 p.m. Eastern against Tunisia.
But there is no shortage of action to bide time until tonight's main events. There are currently 20 events taking place live, ranging from beach volleyball to sailing to fencing.
