There’s a whole lot at stake Thursday night at TD Garden.

The Boston Bruins will host the Tampa Bay Lightning in a battle for the top spot in the Atlantic Division and Eastern Conference. The Lightning effectively have sat atop the standings from wire to wire this season, but the surging Bruins can shake things up with a win over their division rival.

Boston has had Tampa Bay’s number this season, claiming victories in each of the previous two matchups, including a road win March 17. The Bolts also enter the contest reeling, having lost each of their last two games.

As for the lineups, the Bruins are expected to receive a major lift in the form of David Backes, who is expected to return after sustaining a laceration on his right leg that required 18 stitches in the last game against Tampa Bay. Tuukka Rask is set to start in between the pipes for Boston.

Here are the projected lines and defensive pairings for Thursday’s Bruins-Lightning game:
