Former Saudi Arabia star Mohammed Noor has been banned for four years by the Court of Arbitration for Sport over a doping offence.
The 38-year-old tested positive for banned substance Amphetamine in a routine in-competition doping control exam in November 2015.
"The Panel found that the player failed to identify any basis for impugning the reliability or accuracy of the testing laboratory's analysis of his A and B Sample," CAS explained in a statement.
"Moreover, the player could not identify any particular deviation from the WADA [World Anti-Doping Agency] International Standards for Laboratories. Therefore, the appropriate sanction for the player's anti-doping rule violation is a four-year period of ineligibility."
Noor, who has 98 international caps to his name and twice represented his country at the World Cup, is one of the country's most famous sporting figures and has spent 23 years in the top flight with Al Ittihad and Al Nassr.
