This Bruins superstar missed practice.

The Boston Bruins had practice on Monday (Dec. 9), but superstar forward David Pastrnak did not participate. 

While speaking to reporters, Bruins head coach Joe Sacco shared that Pastrnak missed practice due to an "upper-body issue." 

Sacco also announced that Pastrnak will still travel with the team for their upcoming road trip. In addition, Sacco shared that the club is hopeful that Pastrnak will be good to go for the Bruins' matchup against the Winnipeg Jets on Tueday (Dec. 10).

With Pastrnak being the Bruins' best player, they naturally will be hoping that he can play, especially against a tough team like Winnipeg. The 28-year-old forward currently has nine goals and leads the Bruins with 18 assists and 27 points in 29 games.
