Frankie Fredericks
This was the 24th appearance of the event, which was not held at the first Olympics in 1896 but has been on the program ever since. Two of the eight finalists from the 2000 Games returned: silver medalist Darren Campbell and fifth-place finisher Christian Malcolm, both of Great Britain. The 1992 and 1996 silver medalist, Frankie Fredericks of Namibia, had missed the 2000 Games due to injury but returned in 2004. Reigning Olympic champion Konstantinos Kenteris of Greece missed a drug test the day before the Games opened, resulting in his suspension.
