Mexican defender Salvador Carmona, who was kicked out of the 2005 Confederations Cup over doping allegation, has been banned for life by the Court of Arbitration for Sport (CAS) with immediate effect.
CAS said in the ruling published on Friday that Carmona was a multiple doping offender and that Mexican football authorities didn't treat his case properly.
"The player, Jose Salvador Carmona Alvarez, is declared ineligible with immediate and lifetime effect," said CAS.
Carmora was sent home during the 2005 Confederations Cup in Germany along with team mate Aaron Galindo and it was revealed that they tested positive for the steroid stanozolol.
Both received a one-year ban, but during the ban the Cruz Azul Carmora tested positive again in January 2006.
Under international doping laws, multiple offenders get a life ban, but the Mexican federation's disciplinary committee said the player had not been notified properly and wrongly asserted that the b-sample no longer existed.
This ruling was later confirmed by a government panel, but the World Anti-Doping Agency (WADA) challenged it before CAS, which imposed the ban despite pleas from Carmora's lawyers.
"It should be clear that its paramount implication is that those who seek to make their livelihood in professional sports should not violate the anti-doping rules," CAS said in a 23-page statement.
