Senators forward Chris Kelly, scratched for the first four games, will replace Tom Pyatt, who sustained an upper-body injury when he was hit by Boston defenseman Kevan Miller early in Game 4. Pyatt played 17:58 in Game 1 and in the 13-minute range in Games 2 and 3. Kelly, a 36-year-old who was a member of the Bruins from 2011-16, played 82 games in the regular season. "He's a guy that I hated to take out, for the all reasons," Boucher said. "He's a terrific person, a great professional and he's helped us all year. He's been outstanding in our room. That was probably the toughest thing I had to do this year was to sit him out, not because he's not doing a good job, just because the other guys that were available were ahead of him. For the first time of the year we had a full team. It was no fun to do that, so to have him back is exciting for me."
