A defensive blunder by Napoli allowed a stoppage-time equaliser in a 1-1 draw with Torino, hurting the southern club's title chances.

Lazio also dropped back after getting beat 4-0 by Catania, while Fiorentina was the day's big winner after beating Cagliari 4-1 to jump ahead of Lazio into fourth place.

After sitting out Napoli's last two matches with a minor injury, Edinson Cavani celebrated his return by scoring six minutes in at the San Paolo stadium from the edge of the box — his seventh goal in nine appearances this season.

But shortly after Napoli coach Walter Mazzarri was sent off for protests, Torino's Gianluca Sansone equalized with his first Serie A goal after intercepting defender Salvatore Aronica's unwise pass back to his goalkeeper.

Juventus, which was beat 3-1 by Inter Milan in "Italy's derby" Saturday, leads with 28 points. Inter is next with 27, Napoli has 23, Fiorentina 21 and Lazio 19.

Earlier, struggling Pescara beat in-form Parma 2-0 to save the job of its manager, Giovanni Stroppa. The victory promoted Pescara out of the relegation zone, three points clear of Palermo, which was third to last ahead of its match at Roma later.

"It wasn't an easy buildup to the match," Stroppa said. "I read in some places that it would mark my funeral."
