Late Colts owner Jim Irsay privately grappled with a relapse that he and team execs shielded from the public ahead of his death in May at the age of 65, according to a bombshell report.

Irsay, who had long been candid about his battle with substance abuse, “spent the last two years of his life in the throes of a relapse,” The Washington Post reported Thursday, with the report also alleging the late NFL exec was prescribed ketamine from a private doctor.

That doctor, according to the report, “signed Irsay’s death certificate, stating the cause was cardiac arrest.”

Irsay’s daughters have since taken over the Colts in the wake of his death.
