The Pakistan Cricket Board has asked Shahid Afridi to explain comments about the "differences within the tour management in West Indies".
Afridi led Pakistan to a 3-2 win in the one-day series in the Caribbean before complaining about "interference".
"An explanation has been sought from him for reasons to make such statements publically," said a PCB statement.
"PCB will take appropriate action after submission of the tour-report at the conclusion of the tour."
Pakistan, who are coached by former fast bowler Waqar Younis, have still to play two Test matches against the Windies.
But following the conclusion of the ODI series, limited-overs captain Afridi - who quit as Test skipper after one game last summer - has returned home from the Caribbean.
On his return, he said: "I don't like people interfering in my domain. I think it would be better if everyone focused on his job in the team."
