The 30-year-old defenseman signed a one-year contract with the Lightning on Aug. 5, four days after an injury-plagued two seasons with the New York Rangers ended when the final two years of his four-year contract were bought out.
Shattenkirk, who had 28 points (two goals, 26 assists) and was minus-15 in 73 games with the Rangers last season, said he believes the injuries are behind him, and added he hopes joining Tampa Bay will help lift his game; he likely will be paired with 2018 Norris Trophy winner Victor Hedman.
"This is obviously an important year for me to show everyone I'm back to my old self and prove that I can be a player in this League again," Shattenkirk said. "In order for that to happen, you want to put yourself in the best position, and I think this is one of the best positions by far I can be in as a player."
