The Columbus Blue Jackets and NHL Commissioner Gary Bettman are among the mourners scheduled to attend the funeral service for John and Matthew Gaudreau, the siblings who died when they were struck by a suspected drunken driver while riding bicycles in their home state of New Jersey.

The memorial for the Gaudreau brothers was set for midday Monday at St. Mary Magdalen Catholic Church in Media, Pennsylvania. John, an All-Star for the Calgary Flames and Columbus Blue Jackets known as “Johnny Hockey,” and Matthew, who played collegiate hockey alongside his brother at Boston College, died on the eve of their sister’s wedding.
