Mr Boyd says the RSC "have instigated a full investigation"
The Royal Shakespeare Company has delayed its new production of Antony and Cleopatra after the lead actor was "seriously" injured by a prop firearm.
Darrell D'Silva sustained the injury to his hand during technical rehearsals.
The RSC's artistic director Michael Boyd said the actor had undergone surgery and returned to work with his hand in a sling.
"He has shown great grit in returning to the show so quickly after a serious injury," he added.
The play's press night at Stratford-upon-Avon has been postponed from 20 April until 10 May.
Mr Boyd said: "Obviously it's not a decision to be taken lightly, but I would like to give the company the chance to showcase the production to critics when Darrell has had a little more recovery time."
He said the company had "restaged much of the show to accommodate a one-armed Antony."
Mr Boyd added that the RSC "have instigated a full investigation into what happened."
The production also stars Kathryn Hunter as Cleopatra. It is due to run at the Courtyard Theatre in Stratford until 28 August.
