Eales said: "Being CEO of Newcastle United is an extraordinary privilege and I am incredibly proud to be part of the club's exciting journey. However, it has become apparent to me that now is the right time to make this decision so that I can prioritise my health and my family. In the short term, it will be business as usual in terms of running the club's day-to-day operations, and I will give my full support to a transitionary period that will enable the board to carefully assess and appoint my successor. I want to extend my sincere thanks to the club's supporters, ownership, players and staff. I'm proud of what we have collectively achieved and I'm excited to see what's ahead for everyone as the club builds towards a future of sustained success."
