The forward, who signed a three-year contract with the Stars on July 1, is expected to play on the top line alongside Jamie Benn and center Tyler Seguin. Pavelski played the first 13 seasons of his NHL career with the San Jose Sharks and had 64 points (38 goals, 26 assists) in 75 games with the Sharks last season.
David Krejci will be a game-time decision for the Bruins because of a lower-body injury, but the center took part in the morning skate.
Goalie Tuukka Rask, who will start, is 7-2-2 with a 2.04 goals-against average and .936 save percentage in 11 games against Dallas.
It will be the Bruins' first game since a 4-1 loss to the St. Louis Blues in Game 7 of the Stanley Cup Final on June 12.
