Borgstrom has been a healthy scratch for the last three games but will replace Mackenzie Entwistle in the lineup on Tuesday. Borgstrom has scored four goals with three assists (seven points) in 39 games this season.
Bogosian has been out since January 15th due to a lower-body injury but will suit up against his former team on Tuesday. The 31-year-old has scored two goals with four assists (six points) in 23 games this season.
Brown was not on the ice for the Senators' morning skate and will be a game-time decision in St. Louis. Head coach DJ Smith said that Brown has been banged up for a while, so sounds like he's nursing some bumps and bruises rather than something that will keep him out for an extended period of time.
Blueger has been sidelined since January 23rd but was a full participant in Monday's practice and will be a game-time decision vs. the Panthers. Blueger will provide a huge boost to the Penguins' bottom-6, replacing Brian Boyle on the fourth line.
Kase has missed the last four games with an upper-body injury but could be back in the lineup vs. the Kraken. Monitor Kase's status as the Maple Leafs hit the ice for warmups at 7:00 PM ET.
Carrier was not on the ice for the Golden Knights' morning skate and is a game-time decision in Philadelphia. Evgenii Dadonov is expected to move up to the third line if Carrier can't play.
Howden has missed the last two games with an undisclosed injury and did not travel out east for the Golden Knights' five-game road trip. Jake Leschyshyn will remain with the Golden Knights and should be in the lineup in Philadelphia.
It's unclear how Roussel suffered the injury but will be out at least mid-April with a lower-body injury. Hudson Fasching was recalled from the AHL on Monday and one of Fasching, Riley Nash or Liam O'Brien will replace Roussel in the lineup in Detroit.
Hischier is dealing with a lower-body injury and is questionable to play Tuesday vs. the Avalanche. Pavel Zacha will likely shift to centre if Hischier can't go.
