Breaux Greer, an eight-time United States (also known as USA) champion, didn't qualify at the 2008 Olympic trials, finishing 17th and failing to reach the final round.
USA Track & Field placed him on the team. A rule allows for "the selection of an injured athlete who competed in the Olympic trials but did not final ... as long as another athlete is not displaced from the team."
Breaux Greer hurt his shoulder while winning a bronze medal at 2007 World Championships and hadn't thrown in competition until the 2008 Olympic trials.
