“In the midst of my frustration over the expulsion of a player from my country, and feeling that my national team was being harmed, I used offensive and unacceptable expressions against the referee, Fifa, and its authorities,” said Vera.
He added Fifa’s sanction means he can longer work on Paraguayan channels ABC Cardinal and ABC TV’s World Cup coverage, either inside or outside the stadiums.
It also extends to “any type of participation or coverage related to the World Cup”.
Vera sent a letter of apology to football’s world governing body, taking full responsibility for his actions.
“Questioning a rule or disagreeing with a refereeing decision never justifies losing control the way I did,” he added.
“I failed you in something fundamental: maintaining the composure and respect that this profession requires.”
Fifa has not commented on Vera’s claims his credentials have been revoked.
However, news agency Reuters cited sources close to the matter saying football’s world governing body considered Vera’s language unacceptable and his actions falling below standards expected of accredited broadcasters.
