West Ham supporters may be pleased to hear the news.
Indeed, Sullivan has taken heed of the backlash to the Charlie Austin saga, with the Queens Park Rangers striker hitting back at comments he made about his fitness.
Online, West Ham fans had been pleading with Sullivan to simply stop talking - to put it mildly - and it seems they will now get their wish, although the report suggests the co-owner may still speak through the club's official website.
The West Ham owners had taken an admirable approach to become more media friendly but it has unfortunately descended into pure PR incompetence.
The likes of Jack and Dave Sullivan and David Gold will likely continue to provide updates on Twitter but Sullivan Sr's media silence vow appears to be one of necessity now. For the sake of the club's reputation.
