Pietrangelo will miss Thursday's game against Ottawa because of an upper-body injury.

Pietrangelo has two goals, 14 points, 16 hits and 34 blocks in 19 outings in 2024-25. He's listed as day-to-day, so he might still be an option Saturday versus Montreal, but for now, Vegas' blue line is looking thin. The Golden Knights are also missing defensemen Nicolas Hague (undisclosed) and Ben Hutton (upper body). Robert Hagg, who was called up from AHL Henderson on Thursday, is expected to draw into the lineup Thursday due to Pietrangelo's absence.

Johansson will patrol the road crease in Thursday's game versus the Blue Jackets, Gabby Shirley of FanDuel Sports Network Florida & Sun reports.

Johansson will start for the first time since Nov. 3, when he allowed five goals on 32 shots against the Jets. All of the 29-year-old's appearances so far have come on the road, and that will continue Thursday. He's facing a Columbus team that has scored 3.22 goals per game despite a 7-9-2 record.

Knight will protect the road goal versus the Blackhawks on Thursday, Doug Plagens of the Panthers Radio Network reports.

Knight will start for the first time in four games. He took a loss Nov. 12 against the Devils, allowing three goals on 23 shots in that start. The 23-year-old netminder will have an easier matchup Thursday, as the Blackhawks are averaging just 2.32 goals per game.

Greenway (undisclosed) was placed on injured reserve Thursday, per the NHL media site.

Greenway has been dealing with an undisclosed injury for nearly a week, and the Sabres indicated Monday that the 27-year-old is considered week-to-week. It isn't very surprising to see him land on injured reserve, but it isn't yet clear when he'll be in the mix to return to game action. Over 16 appearances this year, Greenway has logged three goals, six points, 40 hits and 16 blocked shots while averaging 16:17 of ice time.

Ovechkin, who was previously listed as week-to-week with a lower-leg injury, is expected to miss 4-6 weeks because of a fracture to his left fibula, the Capitals announced Thursday.

Ovechkin suffered the injury when he collided with Jack McBain during Monday's 6-2 victory over Utah. The 39-year-old Ovechkin was off to a fantastic start to the campaign with 15 goals and 25 points in 18 appearances, including five goals over his past two outings. He's also just 26 markers away from matching Wayne Gretzky for the all-time lead in goals. Andrew Mangiapane is projected to move up to the top line alongside Dylan Strome and Aliaksei Protas during Ovechkin's absence. Ivan Miroshnichenko was recalled from AHL Hershey on Wednesday and is set to make his NHL season debut Thursday versus Colorado.

Martin is expected to start on the road against the Devils on Thursday, per Walt Ruff of the Hurricanes' official site.

Martin has a 1-1-0 record, 2.79 GAA and .891 save percentage in three outings in 2024-25. He posted a 24-save shutout over Ottawa in his last start Saturday. The Devils rank eighth offensively with 3.43 goals per game, so they are likely to be a challenging adversary.

Arvidsson was placed on injured reserve Thursday.

Arvidsson was already ruled out for Thursday's game against Minnesota, but his placement on IR can be retroactive to Nov. 12, so he can be activated whenever he's ready to return. The 31-year-old has two goals and five points over 16 appearances in 2024-25. Arvidsson might get another opportunity on the top six once he's healthy, but he isn't guaranteed that role.

Vanecek (upper body) will not dress Thursday in St. Louis, Max Miller of The Hockey News reports.

Yaroslav Askarov will make his San Jose debut Thursday, while Mackenzie Blackwood will be the backup. Vanecek is in danger of losing his spot on the roster if Askarov is able to excel at the NHL level. Vanecek is 2-5-1 with a 3.36 GAA and an .899 save percentage in 10 games this season.

Kastelic (lower body) is set to play Thursday against Utah.

Kastelic missed Monday's 5-1 loss to Columbus due to the injury. He has three goals, seven points, 24 PIM and 75 hits in 19 appearances in 2024-25. Kastelic's offensive contributions came early in the campaign -- he has just a goal and an assist across his past 15 outings -- and he's projected to center the fourth line Thursday, so Kastelic isn't a great source of points.

Gregor (undisclosed) has been ruled out for Thursday's game against the Golden Knights.

Gregor will be unavailable for a third consecutive game due to his undisclosed injury. It's not yet clear when the Senators expect him to return, but his next chance to do so will be at home against the Canucks on Saturday. Over 16 appearances this year, Gregor has logged two goals, three points and 34 hits while averaging 13:07 of ice time.
