The New York Islanders acquired Robert Bortuzzo in a trade with the St. Louis Blues on Friday that gives the Eastern Conference playoff contenders some much-needed size and depth on the blue line amid injuries.

The Islanders sent a seventh-round pick in the 2024 draft to the Blues for the veteran defenseman, who has only gotten into four games this season while mostly sitting out as a healthy scratch.

The slumping Buffalo Sabres made a minor shake up to their lineup by acquiring fourth-line forward Eric Robinson in a trade with the Columbus Blue Jackets on Wednesday.

The Blue Jackets acquired a conditional seventh-round pick in the 2025 draft in exchange for a seventh-year player having difficulty landing a regular role in their lineup this season. Robinson had just one goal in only seven games a year after scoring a career-high 12 times.

After weeks of speculation, the Calgary Flames traded defenseman Nikita Zadorov to the Vancouver Canucks on Thursday.

The Flames received a 2024 fifth-round pick and a 2026 third-round pick in exchange for Zadorov, who will give the Canucks another top-four defenseman who offers a physical presence. Zadorov is also expected to help with a penalty kill that came into Thursday just outside the bottom 10 of the league with a 76.4% success rate.

The San Jose Sharks acquired defenseman Calen Addison from the Minnesota Wild Wednesday for forward prospect Adam Raska and a 2026 fifth-round draft pick.

Getting Addison comes a day after the Sharks picked up their first victory of the season in a 2-1 win over the Philadelphia Flyers. The win broke an 11-game losing streak which was tied for the longest to start a season in NHL history.

The Pittsburgh Penguins acquired defenseman Jack Rathbone and forward Karel Plasek from the Vancouver Canucks on Tuesday in a trade for defenseman Mark Friedman and forward Ty Glover.

"I would like to thank Jack for all the time he spent with our organization and always pushing hard when competing for a spot," Canucks general manager Patrik Allvin said. "It has been a tough couple of years for him and this will give him a fresh start.

"The two players coming back in this trade will add to our depth as we continue to look at ways to improve our organization."

The Colorado Avalanche acquired defenseman Caleb Jones from the Carolina Hurricanes on Tuesday for forward Callahan Burke.

Jones recorded a career-high 16 points (four goals, 12 assists) and averaged 19:13 of ice time in 73 games last season with the Chicago Blackhawks. He signed a one-year, $775,000 contract with the Hurricanes on Aug. 10 before clearing waivers last week.

The Vancouver Canucks obtained forward Sam Lafferty from the Toronto Maple Leafs on Sunday for a 2024 fifth-round pick.

Lafferty, 28, can be an unrestricted free agent after this season.

"As we work towards becoming a tougher team to play against, Sam will add some grit and sandpaper to our lineup," Canucks general manager Patrik Allvin said in a statement. "We also like the way he skates and can back players off with his speed. He is a good addition to our forward group and has shown he can also use his speed effectively in a penalty-killing role."

The Anaheim Ducks have acquired defenseman Ilya Lyubushkin in a trade with the Buffalo Sabres.

The Ducks sent a fourth-round draft choice in 2025 to Buffalo on Friday night. Anaheim originally acquired the pick from Minnesota in the deal that sent John Klingberg to the Wild last March.

Jeff Petry is on the move -- again.

The veteran defenseman was traded from Montreal to Detroit on Tuesday, in exchange for defenseman Gustav Lindstrom and a conditional fourth-round draft pick in 2025.

The Canadiens also retained 50% of the salary remaining on Petry's contract -- working out to approximately $2.4 million -- which runs through 2024-25.

The San Jose Sharks granted longtime defenseman Erik Karlsson's trade request Sunday, sending him to the Pittsburgh Penguins in a three-team deal that also involves the Montreal Canadiens for a haul that includes veteran forward Mikael Granlund and a 2024 first-round pick.

Along with Granlund and the pick, which is top-10 protected, the Sharks acquired winger Mike Hoffman and defenseman Jan Rutta.
