Saturday's victory over the Ottawa Senators saw the Montreal Canadiens head coach record his 600th career victory, good for 18th on the NHL's all-time list. He trails former Canadiens bench boss Jacques Martin by just 13 victories for 17th all-time.
Julien, who coached the Boston Bruins to a Stanley Cup in 2011, is in his second stint with the Canadiens. He rejoined the Habs in 2017 after an initial stint from 2002 to 2006.
With goaltender Antti Raanta set for an extended absence following surgery Sunday, the Arizona Coyotes will now look to Kuemper to carry the load between the pipes.
"Obviously with Antti out, (Kuemper is) an important piece for us moving forward. I think he's shown to be one of the best backups in the league," Coyotes general manager John Chayka told team reporter Dave Vest.
"Any time there is an injury there is opportunity. There will be an opportunity for him to get an extended look, and he'll get that opportunity to show that he can be a starter in the league."
Chayka added that the Coyotes will not recruit goaltending help while Raanta recovers, according to TSN's Pierre LeBrun.
However, Kuemper needs to return from an injury of his own before he can show his stuff as the starter. The 28-year-old has missed the last seven games with a lower-body ailment and is considered day to day.
Kuemper owns a 4-5-2 record and .914 save percentage across 11 games this year.
In his absence, Arizona has turned to farmhand Adin Hill, who has come away with four wins and a .939 save rate across seven games.
The Coyotes also have Calvin Pickard as an option. The former Philadelphia Flyers netminder was claimed off waivers in late November but has only filled in as the backup since arriving in Arizona.
Prior to the deals, general manager Jim Rutherford floated the possibility of a roster shakeup if there wasn't improvement on the ice. The Penguins currently sit two points back of a playoff position in the Metropolitan Division.
As for Kessel, it's not the first time his name has surfaced in trade talks. Last offseason, a report indicated that the 31-year-old was open to a move to the Arizona Coyotes. Arizona, of course, is coached by Rick Tocchet, who was an assistant in Pittsburgh during the team's Stanley Cup wins in 2016 and 2017.
Kessel is owed $8 million for three more seasons, but $1.2 million of his salary is retained by the Toronto Maple Leafs. His contract also allows him to grant a trade to just eight teams of his choosing.
Across part of four seasons with the Penguins, Kessel has picked up 93 goals and 157 assists in 272 games.
