Bruins' Julien deciding between Soderberg and Daugavins for Game 5

CHICAGO - As the Boston Bruins try to recapture momentum in the Stanley Cup final in Game 5, they could do so with a slightly different lineup. But coach Claude Julien is keeping everyone — including the Chicago Blackhawks — guessing.

It's not clear whether Carl Soderberg will make his Stanley Cup playoff debut Saturday night or whether the Bruins will stick with Kaspars Daugavins on the fourth line with Rich Peverley and Shawn Thornton. Neither player would say if he was playing.

On the Chicago side, injured forward Marian Hossa will play, coach Joel Quenneville said, despite not taking part in the morning skate.

Julien has a choice but did not reveal it, saying he was still "tinkering" between the bigger Soderberg and the more experienced Daugavins.

"Size-wise they're different. One is obviously real gritty along the walls, and the other one is probably more of a play maker," Julien said. "So there's a difference there, and that's where I have to make my decision what I feel I may need."

The injury to forward Gregory Campbell, when he broke his right fibula blocking a shot against the Pittsburgh Penguins in the Eastern Conference final, forced Julien to consider multiple options. Jordan Caron and Jay Pandolfo were also possibilities, but the Game 5 choice is down to Soderberg or Daugavins.

Soderberg is something of a mystery given that he signed with the Bruins late in the regular season and has just six games of NHL experience.

"I haven't seen him that much," Julien said. "He's only played a few games, and that's probably the main reason he hasn't played in the playoffs is we went with some experienced players."

Those players alternated line rushes during Boston's morning skate at United Center. The rest of the Bruins' lineup will remain the same.
