Duguay, who is dating former Vice Presidential candidate Sarah Palin, was diagnosed with Stage 4 colon cancer over a year ago. The cancer has since spread to his liver. His daughter, Shay Thomas, shared a heartbreaking post on Sunday, emotionally pleading with hockey fans to keep the icon in their prayers. 'I wasn't planning on posting anything. but I believe in the power of prayer, and right now, we need all the prayers we can get. And I know so many love him so much. Please keep our dad in your prayers. @noah_duguay @amberstavros' Shay wrote.
