Pregame Notebook: Pivotal Game 4 on Tap - 2013 Boston Bruins Playoffs

BOSTON, MA - The Bruins are set to face off against the Chicago Blackhawks in a pivotal Game 4 at TD Garden tonight. Every game is important, yes, but so far this postseason, no match-up has been more significant than tonight.

A win for the Bruins helps them maintain home-ice advantage and take a 3-1 series lead, while the Blackhawks are hoping to steal a victory from the Garden crowd and head back to their own barn with the series knotted at 2-2.

Both teams held their respective pregame skates Wednesday morning in preparation for the night’s battle. The Bruins’ lineup appeared to be the same as in Game 3. For the Blackhawks, Marian Hossa - a surprise scratch last game - is expected to be back in their lineup, alongside Patrick Sharp and Michal Handzus (see below for projected lineups).

“They’re going to come out hard, it’s a real big game for both teams,” said Bruins’ defenseman Dennis Seidenberg. “The first goal is going to be huge, so I definitely expect a big push from the start.”
