Henry Olonga has been banned from commenting about his protest against Robert Mugabe's regime, according to the player.
Olonga has publicly objected to Robert Mugabe's regime
The Zimbabwe fast bowler, along with team-mate Andy Flower, wore a black armband in his country's World Cup opener to show his opposition to Mugabe.
The pair had previously said the gesture was to highlight the "death of democracy" in the country.
But on Tuesday, Olonga insisted he had been forbidden from talking any further on the matter.
"I would love to talk to you guys," he told reporters at Bloemfontein's Goodyear Park on Monday, "but they don't want me to."
Douglas Hondo has been doing the job for us, and it has been a simple selection issue

When asked who "they" were, he added: "Work it out for yourselves. Work out who doesn't want me to talk about things other than cricket."
The bowler had previously been asked by the national cricket board not to repeat the protest after complaints from the government.
Since then he has not been picked for Zimbabwe, although national selector Andy Pycroft said his absence had not been on political grounds.
"We believe Douglas Hondo has been doing the job for us, and it has been a simple selection issue," said Pycroft.
