Nathan MacKinnon has now lost all his linemates. The Colorado Avalanche announced Tuesday that forward Gabriel Landeskog is out indefinitely with a lower-body injury.

After years as one of the NHL's best bargains, defenseman Roman Josi is getting a significant raise with the Nashville Predators.

On Tuesday, the team announced an eight-year contract extension for Josi, 29, that will average $9.059 million per season annually against the salary cap. The contract begins in the 2020-21 season, when Josi would be the third-highest-paid defenseman in the NHL on average behind Erik Karlsson of the San Jose Sharks ($11.5 million) and Drew Doughty of the Los Angeles Kings ($11 million).

The Detroit Red Wings on Monday acquired forward Brendan Perlini in a trade with the Chicago Blackhawks.

The 23-year-old Perlini has been a healthy scratch for most of this season, appearing in just one game. But he has 45 goals and 27 assists in 200 career appearances with Chicago and Arizona.

Perlini was selected by the Coyotes with the 12th overall pick in the 2014 draft.

The Red Wings parted with defenseman Alec Regula in the deal.

Devante Smith-Pelly, who scored seven goals during the Washington Capitals' Stanley Cup-winning run in 2018, has signed a contract to play in the KHL.

The Kunlun Red Star, which play in China, announced they had signed the 27-year-old winger to a one-year contract.

St. Louis Blues star forward Vladimir Tarasenko will undergo shoulder surgery on Tuesday, the team announced.

Tarasenko will be placed on long-term injury reserve and will be reevaluated in five months, meaning he will miss the majority of the 2019-20 season.

The Pittsburgh Penguins acquired forward Andreas Martinsen and a 2021 seventh-round draft pick from the Anaheim Ducks in exchange for defenseman Erik Gudbranson on Friday, the teams announced.

The Blackhawks have placed defenseman Connor Murphy on long-term injured reserve.

Murphy hurt his groin Tuesday night in a 2-1 shootout loss to the Vegas Golden Knights.

A person familiar with the decision says the Detroit Red Wings have put defenseman Jonathan Ericsson on waivers.

The person spoke on condition of anonymity Tuesday because the Red Wings have not announced the move. The team did announce that Ericsson had been removed from injured reserve.

The Florida Panthers have agreed to a one-year contract with center Brian Boyle, the team announced.

Boyle, 34, finished last season with the Nashville Predators, joining the team from the New Jersey Devils a few weeks before the trade deadline. He had five goals and zero assists in 26 games with Nashville, four of the goals coming on the power play.

Center Nico Hischier and the New Jersey Devils have come together on a seven-year deal worth $50.75 million.

Hischier, 20, was the first overall pick in the 2017 NHL draft. He has two assists in six games this season, having missed Thursday's victory over the Rangers with an injury. The Swiss-born center has 37 goals and 64 assists in 157 career NHL games.
