The team set a Monday news conference in the Scottrade Center concourse, with the public invited.
The 49-year-old Hull set several team records in 11 seasons with St. Louis, with five 50-goal seasons, including a franchise-record 86 in 1990-91. His No. 16 jersey was retired in 2006. He holds records for goals, hat tricks, game-winning goals, power-play goals and shots on goal, and is second in assists, points and short-handed goals.
Hull won a Stanley Cup with the Dallas Stars and has been an executive with the Stars.
