Thursday evening’s performance of “Diana” has been canceled after Erin Davie, who plays Camilla Parker Bowles, suffered a vocal injury.

The musical began previews on March 2. Ticket holders for Thursday night’s performance will be issued a refund or to reschedule.

Performances will resume Friday.

Tessa Alves and Holly Ann Butler are both listed as understudies for Camilla, according to the Internet Broadway Database.

Produced by Grove Entertainment, Frank Marshall and The Araca Group and directed by Christopher Ashley, “Diana” began rehearsals for its Broadway engagement on Jan. 20. It is playing the Longacre Theatre, with an opening night set for March 31.
