The coroner’s inquest into the passing of young midfielder Maddy Cusack has been postponed until December. Additional documents were lodged in court on Thursday, prompting the adjournment. Material presented showed that Sheffield United were informed of Cusack’s disputes with former coach Jonathan Morgan before the club hired him. Lawyers for the family have asked for more time to review the material. Court officials said further delays are likely as additional documents are expected. The case remains open while investigators sort through the new evidence.
