Funeral arrangements are pending for the widow of former heavyweight boxing champion Greg Page.Fifty-one year old Patricia Page died Wednesday evening at her home in south Louisville.Jefferson County Deputy Coroner Gayle Norris says a cause of death won’t be determined until toxicology test results are in, but foul play is not suspected.Greg Page, a one-time World Boxing Association champion, died in 2009 at the age of 50 from complications of head injuries he suffered during a 2001 fight in northern Kentucky.Patricia Page would become her husband’s caretaker and an advocate for stronger safety regulations for the sport, something she spoke about in a 2006 interview."Education, I think, is really important, and that’s one of the things I’ve strived for since Greg got hurt is to get the education out there. There’s a strong need for boxer safety. It’s so disregarded in so many places, and not just Kentucky," she said.New safety rules were later adopted for boxing matches in Kentucky.(Information for this story also came from the Associated Press)
