NHL moves: Sabres sign Ristolainen, Lightning sign Kucherov

The Buffalo Sabres signed defenseman Rasmus Ristolainen and the Tampa Bay Lightning signed forward Nikita Kucherov as NHL teams made final roster moves Tuesday on the eve of the regular season.

Ristolainen signed a six-year $32.4 million contract, while Kucherov signed a three-year deal that averages $4.766 million a year. Both were restricted free agents whose rights were retained by their respective teams in June.

For Buffalo, the signing means the Sabres will have their top defenseman ready for their opener against Montreal on Thursday. The defending Eastern Conference champion Lightning, meanwhile, now have their nucleus intact in preparing to open their season hosting Detroit on Thursday. Kucherov led the Lightning with 30 goals and 66 points in the regular season, and led them again in the playoffs with 11 goals and 19 points.

Their signings left three prominent restricted free agents still without contracts, including Winnipeg defenseman Jacob Trouba, who has asked to be traded. Also unsigned are Anaheim Ducks defenseman Hampus Lindholm and forward Rickard Rakell.

In another move made Tuesday, veteran forward Pierre-Alexandre Parenteau was claimed by the New Jersey Devils a day after being placed on waivers by the New York Islanders. Parenteau is a two-time 20-goal-scorer, who is joining his eighth team in nine NHL seasons. New Jersey freed up roster space by placing defenseman Seth Helgeson on waivers.
