Usada bans distance runner Lukezic
The US Anti-Doping Agency (Usada) has suspended retired distance runner Chris Lukezic for two years for refusing to take an out-of-competition doping test.
Lukezic's ban started on Tuesday. He declined to take the test on April 20, so his results since that date also were thrown out.
USADA says the 26-year-old Lukezic didn't file the proper paperwork announcing his retirement before refusing to take the test. The agency says the 2006 US Indoor 1 500m champion has properly retired from competition since that date.
USADA announced the ban on Thursday.
