It's never a good sign when you type "Matthew Poitras hit" into social media and there's a laundry list of videos of him getting hurt or laid out by contact. The best we've seen Poitras play in a Boston Bruins uniform was in his rookie season in 2023-24, but a right shoulder injury knocked him out in January.
The injury stemmed from some massive contact in a game with Team Canada at the World Juniors, where the Bruins loaned him to get some extra playing time over the holidays. If the front office had known, they would've likely held on to him, as the form he was in during the regular season for the Bruins would've been useful.
