Florida Panthers center Aleksander Barkov will miss his second straight game with an upper-body injury. Coach Tom Rowe had no other update on Barkov, the Panthers' second-leading scorer with 52 points (21 goals, 31 assists). Goaltender Reto Berra will start for the second straight game because of injuries to James Reimer (upper body) and Roberto Luongo (lower body). Berra, who made 27 saves on 33 shots in a 6-2 loss at the Montreal Canadiens on Thursday, is 0-3-0 with an .874 save percentage and 3.38 goals-against average. "I thought once he got his feet under him in Montreal like the rest of the team, he was fine," Rowe said. "But we just talked about playing the right way, adjusting a few things that we did [Thursday] night wrong and be ready for Boston." The Panthers are 5-13-1 in their past 19 games and were eliminated from contention for the Stanley Cup Playoffs on Thursday. Forward Shawn Thornton, who played 480 games for the Boston Bruins from 2007-14 and won the Stanley Cup with them in 2011, will play his last game in Boston; he is retiring after the season. "We've got to have fun. We have nothing to lose," Thornton said. "I've played on the other side playing against teams that were out of it and had nothing to lose, and I think we have to be a loose bunch that plays the right way."
