Hayes’ brother, Philadelphia Flyers centerman Kevin Hayes, also posted a message to Instagram on Tuesday.

"Yesterday I lost my best friend, my brother. My whole life it has always been Jimmy and Kevin or the Hayes brothers. I have followed you around since I can remember and I wouldn’t want it any other way. Whether it was youth hockey, Nobles, Boston College or the NHL, you paved the way for me. You taught me everything I needed to know in order to succeed. You lit up every single room you walked into with your smile and positive attitude."

Our world lost someone special and I don’t know if I will ever be the same but till we meet again, I LOVE YOU JIM!"
