Poitras (undisclosed) missed Wednesday's practice, per Scott McLaughlin of WEEI.
Poitras had 13 goals, 44 points and 48 PIM in 69 regular-season appearances with AHL Providence in 2025-26. He also had a goal in three regular-season outings with Boston last campaign. Provided he's healthy enough to do so, the 22-year-old is likely to begin the upcoming season in the minors.
