BOSTON — Fraser Minten and Casey Mittelstadt each had a goal and two assists and the Boston Bruins beat the Philadelphia Flyers 6-3 on Thursday night. He nearly had another goal late in the second period but was credited with an assist after Nikita Grebenkin scored off the rebound. Flyers goaltender Samuel Ersson was slow to leave the ice as the second period concluded and was ruled out because of a lower-body injury. The Bruins scored the next two goals to open things up. Zacha went to the locker room late in the second period and did not return.
