Colorado Avalanche defenseman Josh Manson (upper body) didn't finish Saturday's 3-2 overtime loss to Vegas, Aarif Deen of Colorado Hockey Now reports. The veteran blue-liner was limited to 11:48 of ice time due to an upper-body injury. Manson has been excellent at both ends of the ice for Colorado this season, recording 31 points (five goals, 26 assists), 99 blocks, and 174 blocks in 79 games. He leads all defensemen in the league with a plus-44 rating. Cale Makar (upper body) is expected to return to the lineup during the final week of the regular season and could take Manson's place.

Montreal Canadiens defenseman Noah Dobson (hand) was forced to make an early exit due to injury on Saturday against the Columbus Blue Jackets. In the second period, he hurt his left hand while blocking an attempt on goal by Blue Jackets defenseman Zach Werenski. Dobson leads the NHL with 188 blocks this season. Unfortunately, his most recent one could end up costing him time just as the playoffs are about to begin. Up to this point, Dobson has featured in all 80 Canadiens games, contributing 12 goals and 35 assists offensively. He is looking at his first absence of the season on Sunday against the Islanders.

Chicago Blackhawks center Frank Nazar (mouth) missed most of Saturday's matchup with the St. Louis Blues after taking a puck to the face. The incident occurred a few minutes into the second period. "I think Frank's going to be all right," Blackhawks head coach Jeff Blashill said postgame. "He had to get some dental work done, but I think he'll be all right." Earlier this season, Nazar was forced to miss a month of action due to a broken jaw from a puck hitting him in the face. It appears he wasn't as severely hurt this time around, though it remains to be seen whether the Blackhawks will use him in their final two games of the season. Nazar is Chicago's third-highest scorer, with 41 points (15 goals, 26 assists) in 64 games. He is seen as a key part of the franchise's future, having signed a $46.2 million, seven-year contract extension ahead of this season.

Chicago Blackhawks winger Andrew Mangiapane (undisclosed) is considered day-to-day after he was hurt during Saturday's 5-3 loss to the St. Louis Blues. The veteran forward left the contest midway through the third period after crashing hard into the net. Chicago faces two more regular-season games against Buffalo and San Jose. Jeff Blashill's team is out of playoff contention, so there's little incentive to rush Mangiapane back for these games. Saturday's matchup was Mangiapane's 10th outing with the Blackhawks. He has posted one goal and one assist since arriving from Edmonton in March. Overall, Mangiapane has notched just 14 points (seven goals, seven assists) in 52 outings. He has disappointed fantasy managers who expected a bounce-back season from him.
