Napoli have been forced into circling the wagons after the players openly revolted against the club.
The Serie A side were held to a 1-1 draw by Salzburg in the Champions League on Tuesday night to extend their winless run in all competitions to four games.
The Napoli squad were due to partake in a training retreat ahead of Saturday night's Serie A game at home to Genoa.
Instead, the players took it upon themselves to return to their homes, and Ancelotti failed to speak to the media after the draw at the San Paolo.
Napoli president Aurelio De Laurentiis held a lengthy conference call with Ancelotti on Wednesday, with Gazzetta dello Sport reporting that De Laurentiis is exploring the possibility of sacking Ancelotti.
De Laurentiis has been seeking legal advice over potential player fines due to their actions.
The club released the following statement on its website regarding the mutiny:
With regard to the behaviour of the first-team squad on Tuesday night, the club announces that it will do everything in its power to protect its economic interests, assets, image rights and disciplinary interests.
The club would also like to make clear that it has entrusted first-team coach Carlo Ancelotti with decision-making responsibility as regards the first-team training camp.
There will be no more press statements for the foreseeable future.
Ahead of that game with Genoa, Napoli sit 7th in the Serie A table with last week's 2-1 defeat away to Roma coming off the back of draws with SPAL and Atalanta.
