Saudi Arabia's most capped footballer Mohammed Noor was handed a four-year ban for testing positive for amphetamine by the Court of Arbitration for Sport (CAS) on Thursday. World football's governing body FIFA had appealed a ruling by the Saudi Arabian Anti-Doping Committee that saw Noor free to play again just five months after the positive test in November 2015.
CAS upheld FIFA's appeal, saying: "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. "Moreover, the player could not identify any particular deviation from the WADA International Standards for Laboratories.
"Therefore, the appropriate sanction for the player's anti-doping rule violation is a four-year period of ineligibility." Noor, whose full name is Mohammed bin Mohammed Noor Adam Hawsawi, underwent an in-competition doping control in November 2015, his A and B samples testing positive for amphetamine.
