Each week of the National Hockey League regular season, we will take a look at some of the most important injuries that have occurred in the last seven days, as well as key players that have returned from injury and updates on the conditions of other fantasy-relevant players (when applicable). Here is this week's batch:

1. Shayne Gostisbehere, D, Flyers (upper-body injury, day to day)

This is a major blow for the Flyers, since the man known as 'Ghost' was producing at more than a point-per-game clip so far in 2017-18. Gostisbehere is suspected to have suffered a concussion last week, though the Flyers have not confirmed that yet. Either way, Philadelphia will probably take their time with the 24-year-old rearguard, who is the team's top power-play quarterback option. That role now goes to Ivan Provorov.

2. Justin Schultz, D, Penguins (concussion, IR)

He was off to a slow start with the Penguins this season, and had been taken off the top power-play unit. Now, Schultz is dealing with a concussion. The good news is he appears to be relatively close to a return to action. His return would hurt the likes of Zach Trotman (who would likely lose his spot in the lineup) and Olli Maatta (who has been quarterbacking Pittsburgh's second power-play with Schultz out)--and MAYBE Kris Letang.

3. Kyle Turris, C, Senators (viral illness, day to day)

The veteran center has now missed three games because of his illness, which might be slight cause for concern at this point. Turris was playing well before leaving the lineup (9 GP, 3-5-8) and is motivated to return to action as soon as possible (since he is scheduled to become an unrestricted free agent next summer). With Turris out, Derick Brassard, Jean-Gabriel Pageau and Nate Thompson are all seeing more minutes at center.

4. Nolan Patrick, C, Flyers (upper-body injury, IR)

Uh-oh. The No. 2 overall selection in the 2017 NHL Draft has missed three games with what is suspected to be a concussion. The 19-year-old wunderkind will probably be treated with kid gloves here, as Patrick is a huge part of Philadelphia's future moving forward. Therefore, Patrick fantasy owners need to practice patience here. Do not expect him to make much of an impact in the first half of his rookie campaign. He may miss a lot of time.

5. Andre Burakovsky, RW/LW, Capitals (broken thumb, IR)

The Capitals were already lacking depth heading into this season, following the exodus of Justin Williams, Marcus Johansson, Daniel Winnik, Kevin Shattenkirk, Nate Schmidt and Karl Alzner. Matt Niskanen is already sidelined for the long term due to injury, and now Burakovsky joins the list of the walking wounded. He had recently been demoted from the second to the third line, so that's a double-whammy for fantasy owners.

6. Cam Atkinson, RW, Blue Jackets (lower-body injury, day to day)

It appears Atkinson's issue is probably a groin or hamstring problem, so he may need a few more games off before he resumes skating with his teammates. The 35-goal man from 2016-17 appeared in all 82 games last season, and only missed one contest in 2015-16. Therefore, it is rare to see him sidelined (despite a lack of optimum size for the NHL game). Oliver Bjorkstrand stands to benefit most from Atkinson's absence.  

7. Kyle Palmieri, RW, Devils (foot injury, day to day)

Palmieri's foot problem has forced him to miss two games (and he is not expected to play in any of New Jersey's next three contests on their current road trip). That is a blow for a squad that had gotten off to a surprisingly strong start in 2017-18. Rookie Swede Jesper Bratt has switched over from left to right wing during Palmieri's injury absence, while veteran Drew Stafford is currently toiling on the Devils' No. 1 scoring line.

8. Nikita Scherbak, RW, Canadiens (knee surgery, IR)

This was a very tough break for the Russian rookie winger, who had been recently promoted to the Canadiens after an excellent start to his AHL campaign with the Laval Rocket. Scherbak played two games on Montreal's fourth line before suffering a knee injury that required surgery. He can now be safely dropped in virtually all leagues, since it will take him quite some time before getting back up to NHL speed. It's really too bad.

9. Brock Boeser, RW, Canucks (foot injury, day to day)

Another rookie right-winger, Boeser is not expected to miss significant time (which is great news for the Canucks). In only eight games so far in 2017-18--he was a healthy scratch in Vancouver's first two games of the regular season--the 20-year-old Boeser has two goals and nine points to lead the team. He is considered a huge part of the Canucks' future, but the future is also now (whenever he gets back in the lineup) for Boeser.

10. Oscar Dansk, G, Golden Knights (undisclosed injury, IR)

Las Vegas is known for off-the-wall scenarios, so the Golden Knights' current goaltending situation fits in well with the rest of 'Sin City'. With starter Marc-Andre Fleury (concussion) and backup Malcolm Subban (lower-body injury) already on Injured Reserve, Vegas lost the services of third-string netminder Dansk this week due to a lower-body injury. Fourth stringer Maxime Lagace and emergency call-up Dylan Ferguson (WHL) are next up.
