The coroner’s inquest into the death 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 conflicts with ex coach Jonathan Morgan before the club hired him. Lawyers for the relatives have asked for an extension to review the evidence. Court officials said more adjournments are likely as more documents are expected. The case remains open while investigators sort through the emerging evidence.
