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