Few athletes in Olympic history have captured the minds and hearts of the public quite like American swimmer Michael Phelps, but fans will likely be watching his historic run come to an end on Friday at the Olympic Aquatics Centre in London.

On Friday, Phelps will be swimming in the last individual competition of his dazzling Olympic career, the 100m butterfly. Coming off an incredible gold medal finish in the 200m individual medley on Thursday, Phelps looks to win his third consecutive gold in the 100m butterfly after winning the semifinal.

In addition to Phelps' big day, Friday also sees the beginning of track and field competition in London. Among the names that will appear on Friday is Algonquin, Ill., native Evan Jager, who's competing in the men's 3000m steeplechase event.

Other key events occurring on Friday include USA-New Zealand in women's soccer and semifinal tennis action, plus key medal events in rowing, track cycling, judo, shooting, gymnastics and weightlifting.
