Inter announced their squad to face Lazio, and the Dutchman was missing from the 23 players named.
Sneijder has refused to sign a new contract with Inter after the Serie A club asked him to extend his contract from 2015 to 2016 for the same overall payment, a move criticised by the world players' union FIFPro.
The midfielder, who was a leading light in the 2010 treble-winning side, has not played for them since the row broke out last month.
Inter are second in Serie A, four points behind champions Juventus.
