LAUSANNE, Switzerland (AP) -- American national team diver Harrison Jones has been suspended for one year after testing positive for marijuana.
Swimming's world governing body FINA says Jones failed a doping control at the U.S. Winter National Championships, held in February at Iowa City, Iowa.
FINA says USA Diving imposed the ban, which took effect on April 6.
Jones, a University of Southern California student, won the 3-meter springboard title at Iowa City.
The 21-year-old native of Spring, Texas, competed in the 2008 Olympic trials but did not qualify to represent the U.S. in Beijing.
