The Pittsburgh Penguins bolstered their blue line on Sunday by acquiring three-time Norris Trophy winner Erik Karlsson from the San Jose Sharks in a trade that also involved the Montreal Canadiens.

The 33-year-old Karlsson heads to Pittsburgh along with forward Rem Pitlick, forward Dillon Hamaliuk and San Jose's 2026 third-round draft pick.

The Sharks acquired forward Mikael Granlund, defenseman Jan Rutta, forward Mike Hoffman and Pittsburgh's 2024 first-round draft pick (top-10 protected).

Montreal landed defenseman Jeff Petry, goaltender Casey DeSmith, forward Nathan Legare and Pittsburgh's 2025 second-round draft pick.

Karlsson was the 15th overall pick in 2008 by Ottawa and spent his first nine seasons with the Senators after making his NHL debut in 2009-10.

He won the Norris Trophy as the NHL’s best defenseman in 2011-12 and 2014-15.

The Senators traded Karlsson to San Jose prior to the 2018-19 campaign, and the seven-time All-Star had a career season in 2022-23.

Karlsson set personal bests with 25 goals and 76 assists to become the first NHL defenseman to record 100 points since Brian Leetch accomplished the feat for the New York Rangers in 1991-92.

In 920 career games, Karlsson has recorded 178 goals and 583 assists. His 761 points rank 21st in the history of the NHL among defensemen.
