F1's governing body is considering banning the 'DRS' moveable wing systems for Monaco.
Italy's Autosprint magazine said the reason for the ban would be the danger of the system's deployment on the famously tight and twisty street layout.
Moreover, DRS would probably be of limited benefit in the Principality, given the lack of a proper straight.
Autosprint said the main fear regarding DRS and Monaco is the free usage of the system in practice and qualifying, and the fact that the curving high-speed tunnel is the most logical place for deployment of the system in the race.
"The final decision will be taken by the FIA after a meeting with the teams and drivers at the Turkish Grand Prix," the report said.
