Turin - Juventus playmaker Andrea Pirlo has been ruled out for the first month of the season with a hip injury, the Serie A champions said on Thursday.
Juventus said in a statement that an MRI had revealed a sprain and that "30 days will be necessary for a complete recovery".
The announcement is an early blow for new coach Massimiliano Allegri, who took over in July after Antonio Conte resigned.
Conte had led Juventus to three successive Serie A titles in as many seasons with Pirlo as the team's main inspiration.
Juventus are away to Chievo in Serie A's opening match on Saturday (1600 GMT).
