Cassidy entered NHL COVID-19 protocol Tuesday, and assistant Joe Sacco assumed primary coaching duties.Marc Staal scored the go-ahead goal in the third period, and Alex Nedeljkovic made 41 saves for Detroit (11-9-3), which has won three in a row and got its 3,000th regular-season victory.”[Nedeljkovic] played well. I will say we played very well defensively,” Red Wings coach Jeff Blashill said. ”We gave up shots, but we didn’t give up a whole bunch of chances. When we did, he did a good job. … I thought we took away the real Grade A chances. I think for me, this would be more of a team defense success than just one player.”David Pastrnak scored, and Linus Ullmark made 14 saves for Boston (11-8-0).”I thought it was a good effort by our guys in the offensive zone tonight,” Sacco said. ”We didn’t pass up a lot of shots. I think we made it a little bit easy on [Nedeljkovic] at times by not getting in front of him enough. … I thought we had some good quality chances. … Unfortunately we weren’t able to finish off some of those chances.”Zadina scored at 5:03 of the second period to give Detroit a 1-0 lead, finishing with a backhand after breaking through Boston’s defense.Video: DET@BOS: Zadina forces turnover, scores on breakawayThe Bruins outshot the Red Wings 25-10 through two periods, including 17-5 in the second.”It’s a night where you want to come away with a win,” Bruins forward Taylor Hall said. ”Those are games in the schedule that when you play like that, you want to come away with points, and obviously that’s something we’ve got to do better at. I feel like on the majority of nights during the season, we control play and haven’t had the record that we want.”Pastrnak tied it 1-1 at 6:20 of the third on a 5-on-3 power play with a one-timer from the high slot.Staal scored his first of the season at 11:33 during a delayed penalty to give the Red Wings a 2-1 lead. Vladislav Namestnikov’s wrist shot from the top of the left face-off circle deflected off Bruins defenseman Mike Reilly in front of the crease, and Staal put in the rebound.”[Staal] is a rock. He’s a guy we lean on for consistency,” Red Wings captain Dylan Larkin said. ”He’s a great locker-room guy. I know the guys have a ton of respect for him and the way he plays the game. It’s great to see him get one. [It was] a huge goal for our hockey team.”NOTES: The Red Wings became the fourth NHL team with 3,000 regular-season wins, joining the Montreal Canadiens (3,479), Bruins (3,252) and Toronto Maple Leafs (3,016). … Bruins forward Jake DeBrusk had one shot and one hit in 10:25 of ice time after he was a healthy scratch Sunday.
