Inter, who are third, listed coach Andrea Stramaccioni's selection on the club website on Saturday.
Sneijder, who is involved in a contract dispute with Inter, did not train with the squad on Friday and the reason given was because he had a leg muscle problem, however, his wife, Yolanthe Cabau wrote on Twitter: "He's not injured! Wesley is just fine."
Stramaccioni was visibly angered during Saturday's news conference when reporters asked him why the club said the Dutch international was injured.
"The only thing that matters to me, is what the player says to my face, and as for everything else, including Twitter, I really couldn't give a damn," he said.
Inter have 31 points, two behind Napoli with Juventus top of the table on 35.
