Zack Smith, who missed the last two periods of Game 3 because of an upper-body injury, is feeling better than expected and will be a game-time decision. Senators coach Guy Boucher said Pyatt, who sustained an upper-body injury against the Boston Bruins in the first round, will play, but it hasn't been decided who Pyatt will replace. Wideman will play for the first time since Game 5 of the first round against the Bruins on April 21, replacing Claesson. … Nash did not practice Wednesday or skate Thursday morning, but Vigneault said he was fine.
