Mutter was placed on waivers by the Bruins on Sunday, per Elliotte Friedman of Sportsnet.
Mutter was deemed the odd-man out among Boston's depth forwards Sunday and will head to waivers. The 25-year-old winger was acquired by Boston midway through the 2025-26 campaign, and he posted a goal and 23 PIM across 12 regular-season games with AHL Providence. If the gritty forward is not claimed over the next 24 hours, he will be eligible to return to Providence ahead of his first full season in Boston's organization after four years with AHL Milwaukee.
