Matiss Kivleneiks will be honored when the Columbus Blue Jackets take the ice on opening night ... with the late goalie's family set to attend the tribute.
The 24-year-old tragically died after suffering serious damage to his lungs and heart during a fireworks mishap at a Jackets coaches 4th of July party.
Matiss -- who signed with the Blue Jackets in 2019 -- was deemed a hero by his teammate, Elvis Merzlikins, for his actions during the fatal incident ... saying MK saved his family from the firework.
