Juventus coach Antonio Conte is facing a 15-month suspension for his role in the in the "Calcioscommesse" match-fixing scandal, Italian agency Ansa said Thursday.
Conte is accused of failing to notify authorities about match-fixing in two games when he was in charge of Siena during the 2010-11 season.
The Italian Football Federation (FIGC) on Wednesday rejected Conte's proposal to plead guilty in exchange for a three-month ban.
The ruling throws Conte's return to the Juventus sidelines in November into doubt, leaving the Serie A team in a critical situation.
The matches in question, which took place when Siena was in Serie B, were against Novara and Albinoleffe.
The fall-out of the so-called "Calcioscommesse" -- football betting -- investigation has been felt since last year with several high-profile names implicated.
