Fr Artur Niemira, chancellor of Włocławek diocese, told the Polish Catholic news agency KAI that local Bishop Wiesław Mering had decided to impose the disciplinary measures in order to prevent the spread of scandal among the faithful.
KAI said the archbishop had refused to mention Pope Francis's name when celebrating Masses. It added that the measures would remain in effect until the Holy See issues a judgment on the case.
The archbishop has repeatedly criticised Pope Francis. Last year the Polish journal Więź reported that he had called Francis a "usurper and heretic."
Więź said the archbishop had given a book-length interview to the author Stanisław Krajski. The journal quoted the archbishop as saying: "Bergoglio preaches untruth, preaches sin, and does not preach a tradition that lasted so many years, 2,000 years... He proclaims the truth of this world and this is the truth of the devil."
In January, the archbishop appeared on the Polish television show Warto rozmawiać, prompting criticism from the Polish bishops' conference. The bishops' spokesman Fr. Paweł Rytel-Andrianik noted that the archbishop is not a member of the Polish bishops' conference.
"Therefore the statements of Archbishop Lenga cannot be identified in any way with the Polish episcopal conference," he said. "They cannot be treated as positions of Polish bishops."
