Blatter said in a statement Monday it is “difficult” to accept but that “the way the case progressed, no other verdict could be expected.”
The former FIFA president, who was banned for approving a $2 million payment to Michel Platini in 2011, said he will accept the decision.
“I have experienced much in my 41 years in FIFA. I mostly learned that you can win in sport, but you can also lose,” Blatter said. “Nevertheless I look back with gratitude to all the years, in which I was able to realize my ideals for football and serve FIFA.”
The verdict ends Blatter’s hopes of becoming honorary president of the soccer body he left in disgrace.
Blatter could have appealed the CAS ruling to Switzerland’s supreme court. It can annul verdicts if legal process was abused.
Still, his legal problems are far from over.
Blatter now faces a separate FIFA ethics investigation into suspected bribery linked to multimillion dollar bonuses in top executives’ contracts. Swiss prosecutors also opened criminal proceedings against Blatter for the Platini payment, and a sale of World Cup television rights.
Blatter denies any wrongdoing.
Blatter said Monday it was “incomprehensible” that his claim of having a verbal agreement in 1998 was not accepted “in spite of my testimony to the contrary and the testimony given by other witnesses.”
