Vessey warned, win forfeited

Maggie Vessey, an American 800-metre runner hoping to qualify for her third trip to the World Athletics Championships, was given a doping warning Friday by the US Anti-Doping Agency.
USADA announced that Vessey, who turns 31 on Sunday, tested positive for the prohibited substance Canrenone during a urine test conducted at the IAAF World Challenge in Zagreb, Croatia, last September.
Vessey won the 800m title at the event in 1min 59.61 sec but the victory was forfeited because of the positive doping test.
The banned drug was discovered in a prescribed medication that Vessey was taking in a theraputic dose under a doctor's care.
