Pettersson has missed the last three games while in COVID-19 protocol but was on the ice for Wednesday's practice and will be a game-time decision on Thursday. Pettersson skated on the third pairing with Chad Ruhwedel (also a game-time decision) in the session.
Chytil was hurt in his first shift on Saturday and will not play Monday vs. the Panthers. With Chytil out, Kevin Rooney will likely serve as the Rangers' No.3 centre.
Chytil exited Saturday's game in Calgary after his first shift and did not return. Head coach Gerard Gallant did not have an update on Chytil's status post-game, so his availability for Monday's game remains in question. Julien Gauthier, who is currently the only reserve forward on the Rangers' roster, will likely replace Chytil if he can't play.
Sherwood has been great in the AHL this season, leading the league with seven goals and tied for third in points (10). With Mikko Rantanen and Andre Burakovsky likely unavailable, Sherwood will make his season debut on Wednesday. The 26-year-old has 16 points (6G / 10A) in 76 career NHL games.
Hronek has been a healthy scratch for the last two games but will replace Gustav Lindstrom (undisclosed) in the lineup on Wednesday. Hronek has one assist and four shots on goal in four games this season.
Joshua comes up to replace Ryan O'Reilly, who was placed on the COVID-19 reserve list on Tuesday. Joshua had one goal in 12 games with the Blues last season.
