BUFFALO, N.Y. (AP) — The Buffalo Sabres continued locking up their young core of players by signing defenseman Mattias Samuelsson to a seven-year, $30 million contract on Wednesday.

The 22-year-old Samuelsson established himself as one of the team’s top blueliners in his second NHL season last year. He finished with 10 assists in 42 games after missing the start of the season with a leg injury.

At 6-foot-4 and 231 pounds, Samuelsson plays a defense-first role to complement Buffalo’s more offensive-minded blueliners such as Rasmus Dahlin and Owen Power. He has yet to score a goal in 54 NHL games, but had five goals in 45 games with the Rochester Americans.

Samuelsson is from Philadelphia and was selected by Buffalo with the 32nd pick in the 2018 draft, the same year the franchise picked Dahlin first overall. He is the son of former NHL defenseman Kjell Samuelsson, who played for Pittsburgh, Philadelphia, the New York Rangers and Tampa Bay during a 14-year career.

Samuelsson’s signing comes a little over a month after Buffalo signed 24-year-old center Tage Thompson to a seven-year, $50 contract, and on the same day the team signed coach Don Granato to a 2-year extension.

The Sabres open their season Thursday night at home against Ottawa.
