AC Milan will be able to play Udinese in front of their own fans after a ruling that they must play one match behind closed doors was overturned.
Serie A bosses had issued the punishment after fans were found guilty of "insulting" chanting towards Juventus fans in a 3-2 away defeat.
But the San Siro will be open to fans when Udinese visit on 19 October.
An Italian Football Federation statement said the stadium ban had been lifted pending further investigation.
Milan had also been fined 50,000 euros (£42,000) but that too has been suspended on appeal.
The statement added: "The Federal Court of Justice has suspended the sanctions on an appeal filed by Milan against the closure of the Stadio Giuseppe Meazza (San Siro) for one match and a fine of 50,000 euros.
"The Federal Court of Justice asks the Federal Prosecutors Office to gather every possible piece of evidence."
Serie A has clamped down on racist and discriminatory chants this season, with three other clubs - Roma, Lazio and Inter Milan - receiving partial stadium bans after their fans abused black players.
Meanwhile, Milan defender Philippe Mexes has also been banned for four matches by league authorities.
The 31-year-old France international received three games for punching Juventus defender Giorgio Chiellini and an additional one match for being sent off later in Sunday's defeat.
