Mike Fisher has decided to end his retirement from the NHL and rejoin the Predators, with whom he played in the Stanley Cup Final last season. He's expected to sign a contract for the rest of the season ahead of the Feb. 26 NHL trade deadline, when postseason rosters must be set.

He practiced in full Predators gear on Wednesday morning at Bridgestone Arena.

Fisher will turn 38 on June 5. He's the fifth-leading goal-scorer in Predators history with 109.

Jaromir Jagr cleared waivers and has been assigned to HC Kladno of the Czech 1 Liga in the Czech Republic, the Flames announced Monday.

"Jaromir's career speaks for itself," Flames GM Brad Treliving said in a news release. "He is a legend in our sport and we are very appreciative that he selected Calgary to pursue his career in the NHL. Regretfully, with a late start to his season combined with nagging injuries, he wasn't in a position to perform at the level both he and our team had hoped.

"During his short time in Calgary, Jaromir demonstrated tremendous leadership and professionalism, especially with our young players. We thank him for his contributions to our group both on and off the ice."

Ever since the Islanders relocated to Brooklyn's Barclays Center in 2015, many of their die-hard fans have clamored for an eventual return to their first home, the 46-year-old Nassau Coliseum.

Those prayers have finally been answered -- on a temporary and part-time basis.

For at least the next three seasons, the Islanders will split their home games between Barclays and Nassau while a new arena is constructed at Belmont Park racetrack. New York Governor Andrew Cuomo said the team will play half of their 120 home games at each arena ahead of the new building's expected opening in three years. The Islanders confirmed that 12 of their 41 regular-season home games in 2018-19 will be played at Nassau Coliseum. 

Future Hall of Famer Jaromir Jagr was placed on waivers by the Calgary Flames on Sunday.

Jagr, 45, was limited to 22 games this season due to injury after signing with Calgary in October 2017. He has one goal and six assists and last played on Dec. 31.

As criticism of the NHL coach's challenge grows louder around the league, commissioner Gary Bettman wants a little less scrutiny and a little more common sense in these reviews.

"We need to give a refresher to the officials. Take a good look, a quick look, but don't search it to death," Bettman said Saturday ahead of the NHL All-Star skills competition in Tampa.

Sharks star Joe Thornton will likely miss "several weeks" with an MCL-related injury to his right leg, GM Doug Wilson said on Wednesday.

Thornton, 38, came off the ice with 40 seconds left in the third period of the Sharks' 5-4 overtime loss to the Jets on Tuesday night in San Jose. Teammate Mikkel Boedker fell on his right leg as Thornton was tumbling to the ice after chasing down a puck in the neutral zone.

Wilson said, at a minimum, Thornton will miss two weeks. According to The Athletic, the Sharks are still waiting for the results of an MRI for a determination on surgery or next steps for Thornton.

The Los Angeles Kings have traded goaltender Jeff Zatkoff to the Columbus Blue Jackets in exchange for future considerations, Kings Vice President and General Manager Rob Blake announced today.

Marc Savard has officially retired from the NHL, seven years to the day of his final appearance in an NHL game.

The Blue Jackets have traded defenseman John Ramage to the Coyotes in exchange for future considerations, club General Manager Jarmo Kekalainen announced today.

He has skated in one game with the Blue Jackets in 2015-16 and added 14-47-61 and 171 penalty minutes in 170 games with the Monsters since signing as a free agent with Columbus on July 3, 2015.
