What happened: A potential trade target for the Boston Bruins has come off the trade market. The development narrows Boston's external options as regular-season competition moves forward.

Why it matters: Roster flexibility remains critical as teams gauge needs across the opening weeks of the campaign. Any adjustments to the lineup will now rely on remaining trade avenues or internal development.

What to watch: The Boston Bruins host the Vegas Golden Knights on Monday at 7:00 PM ET.
