Rossi makes cut in Italy's provisional squad
Rossi has been plagued by knee problems and damaged the anterior cruciate ligament in his right leg in January, leaving his availability for the World Cup into doubt.
However, after featuring as a substitute in this month's Coppa Italia final and two subsequent Serie A fixtures, the 27-year-old has been selected by national coach Cesare Prandelli.
Antonio Cassano, who last represented Italy in the final of UEFA Euro 2012, is another player to have made the cut.
There are also call-ups for Torino's Ciro Immobile, Serie A's top scorer this season, and Christian Maggio of Napoli, who has recovered from surgery on a partially collapsed lung.
Genoa goalkeeper Mattia Perin, Verona's Brazil-born midfielder Romulo and Torino defender Matteo Darmian are the three uncapped players in the party, while Giorgio Chiellini is included despite receiving a three-match domestic ban for elbowing Miralem Pjanic in Juventus' weekend victory over Roma.
However, Stephan El Shaarawy, another player hampered by injury in recent months, Alberto Gilardino and Luca Toni - the scorer of 20 league goals this season - have missed out, together with Pablo Daniel Osvaldo and Emanuele Giaccherini.
Parma goalkeeper Antonio Mirante will join Italy's 30-man squad for a training camp in Coverciano as injury cover.
Prandelli's men play friendlies against the Republic of Ireland and Luxembourg before facing England, Costa Rica and Uruguay in Group D at the World Cup.
