Boston Bruins coach Jim Montgomery has learned to normalise the success of his team this season, even as they made NHL history on Thursday.

In beating the Buffalo Sabres 7-1, the Bruins improved to 48-8-5 and 101 points for the year.

The Bruins passed 100 points in their 61st game, beating the previous record set by the 1976-77 Montreal Canadiens, who reached that mark in 62 games.

But Montgomery was relatively unmoved by the achievement, having grown used to his brilliant team setting the benchmark over the course of the campaign.

"For me personally, it doesn't mean that much," the Boston coach said. "We try to stay in the moment, and we've been doing that.

"We started off 11-1, and I was like, 'man, that's unreal,' and then you catch yourself and you go back into the moment, and we've probably gone 11-1 every 12 games to have the record we have.

"It's been really amazing to watch them want to be great, because with the schedule and everything, it's really impressive."

The latest win came on an eventful day for the Bruins, who tied David Pastrnak to an eight-year, $90million extension earlier on Thursday.

Pastrnak then had a goal and two assists against the Sabres just hours later.

The Bruins also traded for forward Tyler Bertuzzi from the Detroit Red Wings ahead of Friday's deadline.

Buffalo Bills co-owner Kim Pegula is recovering from suffering a cardiac arrest last June, but "where she ends up is still unknown".

American tennis star Jessica Pegula, the world number four, provided an update on her mother's condition in a long Players' Tribune article on Tuesday.

The five-time grand slam singles quarter-finalist revealed her sister, Kelly, saved their 53-year-old's mother live by giving her CPR after their father woke up to her going into cardiac arrest nine months ago.

Kim, co-owner and president of both NFL franchise the Bills and NHL team the Buffalo Sabres, is back at home and doctors are "blown away" by her "miracle" recovery.

She is, however, suffering from significant expressive aphasia and significant memory issues and the family have come to the realisation that she is unlikely to resume her roles with the Bills and Sabres.

Jessica revealed that three months before her mother fell ill, her sister had decided to learn CPR.

She wrote: "Kelly called me one day and said she was going to get her CPR certification as a requirement for a job she wanted. I said: 'No way, I have been meaning to do that but haven't gotten around to it.”

"She relayed to me how nervous she was about it and hoped she passed the class. I remember her telling us what she was doing in our family group chat, and my mom even responded: 'Nice Kells! Now if we have a heart attack, you can revive us.'"

She added: "Today, my mom is still in recovery, and although it is the same answer every time someone asks me, it is true, she is improving every day. She is dealing with significant expressive aphasia and significant memory issues.

"She can read, write, and understand pretty well, but she has trouble finding the words to respond. It is hard to deal with and it takes a lot of patience to communicate with her, but I thank God every day that we can still communicate with her at all. The doctors continue to be blown away by her recovery, considering where she started, and her determination is the driving force of that."

Jessica was a quarter-finalist at the Australian Open last month, having been considering whether she should call time on her career.

She stated: "Suddenly, I went from 'Let's celebrate top 10 in the world' to 'Do I need to start thinking about my career after tennis a lot sooner than I thought?' 'Does my dad and family need help?' 'Maybe I should just go back to school and work for the family.'

"I am 28 and I take pride in being able to handle every situation thrown at me, but this was A LOT."

She was also hit hard by seeing Damar Hamlin collapse on the field while playing for the Bills last month.

"Then in January we came to some bizarre, messed-up, full circle moment." she wrote. "Buffalo Bills player Damar Hamlin suffered a cardiac arrest on the field during the Monday night game against the Cincinnati Bengals. My stomach sunk because it felt like the exact same thing all over again."

Last year's French Open women's doubles runner-up continued: "It has been a tough year, but at the same time I feel lucky and blessed. I am thankful she is still with us when other families may not have been so lucky.

"That she even had a chance at recovery when the first week in the hospital seemed so dim. Thankful for the doctors that aided in her recovery. Thankful that she is now home, that she gets to watch the Bills, Sabres and my tennis matches. She never watched my matches before, because she got too nervous. Now she watches all of them.

"Thank you to the Buffalo community for your patience. I know you have wanted answers and it took us a while to get there, but it finally felt like it was time. Thank you to everyone who has respected privacy and shown me and my family tremendous support throughout this ongoing journey."

The Buffalo Sabres will honour long-time goaltender Ryan Miller by retiring his No. 30 jersey next season.

Miller joined the Sabres in 2002-03 and spent 10-plus seasons with the franchise, becoming Buffalo's leader in wins (284) and games played by a goaltender (540).

He went on to eventually set the record for wins by an American-born goalie (391) and retired after the 2020-21 season.

The team made the announcement by releasing a video on Friday, which showed Miller being informed of the honour while touring the Sabres' arena with his wife, mother, sister and two children.

The announcement coincided with Miller's trip to Buffalo where he took part in a news conference to discuss being inducted into the Buffalo Sports Hall of Fame later this year.

"Ryan Miller embodied what people in Western New York expect from those who wear a Buffalo Sabres uniform: on-ice excellence, commitment, and authentic love for this community," Sabres general manager Kevyn Adam said.

"We are thrilled for Ryan to take his rightful place alongside his fellow Sabres legends and look forward to celebrating his career."

Miller, who also played for the St Louis Blues, Vancouver Canucks and Anaheim Ducks, had his best season in 2009-10 when he won the Vezina Trophy as the league's top goaltender and earned Olympic MVP honours for helping the United States to a silver medal at the Vancouver Games.

Miller joins NHL Hall of Famer Dominik Hasek as Sabres goalies to have their numbers retired. Miller's 391 career wins rank 14th in NHL history, two ahead of Hasek.
