The Chicago Blackhawks suffered a 4-0 shutout loss to the Columbus Blue Jackets on Wednesday night, in their final game before the Olympic break. The Blue Jackets extended their winning streak to seven games, while the Blackhawks struggled to generate offense. Here are three takeaways from the game:

1. Injury Concerns Loom Over Blackhawks

The Blackhawks already face a tough season with key players like Connor Bedard and Frank Nazar sidelined with injuries. The game against Columbus brought more injury woes, as Wyatt Kaiser left the game after an awkward collision. Kaiser, who has been a valuable asset to the team, especially in mentoring young defensemen, took an "ugly spill" and needed assistance off the ice. Colton Dach was also ruled out of the game early after getting hurt in the second period. The extent of Kaiser's injury is unknown, but his absence would be a significant blow to the Blackhawks' defensive core.

2. Offensive Struggles Continue for Chicago

The Blackhawks' offensive struggles were evident as they were shut out by Jet Greaves, who recorded his second shutout of the season with 21 saves. The team failed to capitalize on opportunities and couldn't find a way to solve the Blue Jackets' defense. The Blackhawks have struggled to score goals consistently throughout the season, and this game was no exception. With key offensive players already injured, the remaining forwards need to step up and provide more scoring threat.

3. Olympic Break Comes at a Crucial Time

With a multitude of injuries and a struggling offense, the Olympic break comes at an opportune time for the Blackhawks. The team can use this time to rest, recover, and regroup for the remainder of the season. The break will allow injured players to heal and give the coaching staff time to evaluate the team's performance and make necessary adjustments. The Blackhawks have a number of young players who are not used to the grind of a full NHL season, so the break will also give them a chance to recharge. The Blackhawks won't practice again until Feb. 18, giving them two weeks to recover.

The Blue Jackets, on the other hand, are heading into the Olympic break on a high note. Zach Werenski became the first defenseman to score 20 goals before the Olympic break. The Blue Jackets' impressive run has put them back in playoff contention.
