Grzelcyk will miss his fourth straight game on Thursday and will not travel with the team to Lake Tahoe, ruling him out of Sunday's game vs. the Flyers.
Karlsson, who has missed the last two games, did not travel with the team to St. Louis, so he'll miss at least two more games with a lower-body injury. Tomas Hertl may have slipped up on Wednesday, saying that Karlsson is dealing with a groin injury that could keep him out for a bit.
Beauvillier has been out since January 24th but will play Tuesday in Buffalo. Beauvillier will most likely replace Leo Komarov in the lineup and Michael Dal Colle on Brock Nelson's wing in his return. Beauvillier picked up one assist and four shots on goal in five games before getting injured.
The Sharks' blueline depth will be tested on Monday with both Karlsson and Radim Simek out. Frederik Claesson will make his season debut replacing Karlsson.
Acciari did not travel with the team as they start a four-game road trip tonight in Tampa Bay and is expected to miss the entire trip. With Acciari out, look for Juho Lammikko to draw back into the lineup.
Barry Trotz was speaking in riddles this morning, telling reporters that "we're all healthy" and that Beauvillier is "close to able to play" but would not specifically say if he's in on Monday. Consider Beauvillier a game-time decision and monitor his status when they hit the ice for warmups.
Puljujarvi missed Thursday's game due to being added to the COVID-19 reserve list but was quickly activated, signalling a false positive. Puljujarvi returned to Edmonton from Montreal on a charter flight and is eligible to participate in tomorrow's practice.
Beauvillier was originally listed as a game-time decision for Saturday's game but was ruled out after the morning skate. That means either Leo Komarov will remain in the lineup or he'll be sent down after clearing waivers and someone like Kieffer Bellows will be recalled.
Beauvillier was on the ice for Friday's practice and Leo Komarov was placed on waivers, seemingly paving the way for Beauvillier to be activated from IR and play Saturday. The Islanders have gone 2-2-3 in the seven games without Beauvillier.
Grzelcyk suffered a lower-body injury in Wednesday's overtime win over the Rangers and is unlikely to play on Friday. Grzelcyk has had a very difficult time staying healthy this season, having missed six of the first 12 games.
