Qatari middle-distance runner Hamza Driouch has been suspended two years for a doping violation.
The IAAF says the 20-year-old athlete was sanctioned for irregularities in his biological passport, which tracks a competitor’s blood profile for signs of doping.
The IAAF says the suspension will last until Dec. 30, 2016, ruling Driouch out of a possible appearance at the Olympics in Rio de Janeiro.
