"Making my way to the NHL and playing in the best league in the world for 13 seasons has been a dream come true. I will be forever grateful for the experiences and friendships that I have gained over the course of my career, including capturing the Stanley Cup in Tampa in 2004," said Kubina. "Thank you to Phil Esposito for drafting me and giving me a chance to play for the Lightning. I also would like to thank my family and friends for their support throughout my hockey journey."
