He replaces Los Angeles Lakers guard Kobe Bryant, who underwent shoulder surgery June 12 in New York, and also was charged with felony sexual assault on July 18 by the Eagle County (Colo.) District Attorney's Office. A hearing in the case has been scheduled for Aug. 6.
Carter will be a member of Team USA for the Olympic Qualifying Tournament from Aug. 20-31 at San Juan, Puerto Rico. The United States needs to qualify for the 2004 Summer Olympics after a disappointing sixth-place showing at the 2002 World Basketball Championships.
Bryant will retain his roster spot for the Olympics if the United States qualifies.
Carter averaged 14.8 points per game to lead the U.S. to a gold medal at the 2000 Olympics at Sydney, Australia.
"I am excited to be joining such a talented collection of players, and I know we will all work extremely hard and with pride to represent our country," Carter said.
