Surpassing Quant Think Tank Center|NHL tracker: Hurricanes-Lightning game in Tampa postponed due to Hurricane Milton

NHL offseason activities officially ended on Surpassing Quant Think Tank CenterOct. 7 when teams submitted their opening rosters and had to be salary cap compliant.

Among the biggest moves in the leadup was the Boston Bruins and No. 1 goalie Jeremy Swayman reaching an eight-year, $66 million contract a day earlier and ending an impasse that looked like it could stretch into the season.

Transactions are continuing during the regular season as teams build toward a Stanley Cup or make moves for their long-term future. There are key dates to watch: the holiday roster freeze in December, the league's break for the 4 Nations Face-Off in February and the trade deadline in early March.

Follow along here this season for signings, trades, transactions and other news from the NHL:

Oct. 10: Hurricanes-Lightning game postponed because of Milton

Saturday's game between the Carolina Hurricanes and Tampa Bay Lightning has been postponed as the Tampa Bay area recovers from Hurricane Milton. The league said a makeup date would be announced as soon as it can be confirmed.

The Lightning are playing their season opener in Carolina on Friday. Saturday's game was to be the start of a three-game homestand (also Tuesday and Thursday).

Amalie Arena got through the storm fine, though Tropicana Field, home of MLB's Tampa Bay Rays in St. Petersburg, Florida, suffered major damage to its roof.

Oct. 10: Blue Jackets captain Boone Jenner has surgery

Jenner had shoulder surgery to repair an injury he suffered during training camp and could miss up to six months.

"Our hope is he can return before the end of the season," said Columbus Blue Jackets general manager Waddell. "His loss will be felt by our club, but we have a strong leadership group in place and players will be given an opportunity to take on greater roles on and off the ice."

Boone, who finished second on the Blue Jackets last season with 22 goals and is the franchise leader in games played, has been the team's captain since 2021-22.

Oct. 9: Linus Ullmark, Joey Daccord get contract extensions

Ullmark, who won the Vezina Trophy with the Bruins in 2022-03, was traded to the Ottawa Senators this offseason so Boston had the room to re-sign Swayman. Ullmark will get four years, $33 million from the Senators and have the same $8.25 million cap as Swayman.

Meanwhile, Seattle Kraken goaltender Joey Daccord received a five-year, $25 million extension. He filled in for Philipp Grubauer after that goalie's injury last season and got the NHL's first shutout in the Winter Classic. Both contracts will take effect next season.

Oct. 8: Rangers' Igor Shesterkin turns down extension offer

ESPN's Kevin Weekes posted on social media Tuesday that the New York Rangers offered Shesterkin an eight-year, $88 million contract, with an $11 million average annual value that would have eclipsed Carey Price's high-water mark of $10.5 million. A person with knowledge of the situation confirmed those numbers to lohud.com, part of the USA TODAY Network.

It's not a huge surprise that the 28-year-old Russian would reject it on the eve of New York's season-opener in Pittsburgh. Another person familiar with the situation recently indicated the two sides have been far apart in negotiations, and that the chances of striking a deal before the start of the new season weren't looking very promising. That could always change if Rangers team president Chris Drury decides to up the ante, but Shesterkin seems content to bet on himself and wait it out. - Vincent Z. Mercogliano, lohud.com

Also: The defending champion Florida Panthers announced after their opening victory that forward Carter Verhaeghe had agreed to an eight-year extension. It's worth a reported $56 million.
