‘Andy passed away peacefully this morning beside his loving family,’ a statement shared to his X account read Thursday morning.
‘We thank you all for your support and love over the years. This was a genuine space of laughter and kindness. Please carry this spirit on in honor of Andy.

Isaac was diagnosed with Hodgkin’s Lymphoma in 2006 and became a popular online figure
Just last month, he announced in a final social media post that he was entering hospice care
‘Having cancer since 2006 has finally taken its toll on me. It has finally stripped me of quality of life,’ Isaac wrote.
‘I have decided on hospice care. Life has been a struggle these last few months and years. I hope I can find some peace in hospice. I may keep a journal of my final days.
‘I’m not sure yet. I’m tired and I’m in pain. I have a horrible foot infection that is preventing me from walking, and I just don’t have the strength to do all the last-minute things I want. But I’ll try.
‘I hope I gave you all a positive outlook on life. I hope I made even the smallest impact. Be kind to each other. I love you all. Truly, I do.’
Isaac was diagnosed with Hodgkin’s Lymphoma in 2006 and, as he told The Athletic , he started writing shortly after.
He became a popular online figure thanks to his humor and passion for the Detroit Lions (NFL), Pistons (NBA), Tigers (MLB), Red Wings (NHL) and Michigan State University.
Isaac has posted nearly 50,000 times on X since 2009, ‘for sports, for the Lions and for the Pistons and for the Tigers and for MSU and so on’ he added.
Tributes flooded in for Isaac as his fellow sports fans honored him in the responses to his family’s statement.
