Armia scored a goal on three shots, delivered one hit and blocked two shots in Thursday's 7-4 win over the Devils.
Armia spun and beat Andrew Hammond over his left shoulder to give the Canadiens a 4-2 lead late in the second period. The tally snapped a seven-game goal drought for Armia, who has just five markers in 55 games this season. The 28-year-old forward is relegated to bottom-six duty.
