The Devils today placed rookie defenseman Adam Larsson on injured reserve retroactive to Feb. 2.

The team also recalled defenseman Peter Harrold from Albany (AHL).

Larsson, who has missed the last seven games with a bruised lower back suffered when he was hit by P.K. Subban of the Montreal Canadiens, will be lost for a much longer period than originally expected.

In 48 games this season, Larsson has 16 points (two goals, 14 assists). He missed the All-Star weekend's SuperSkills competition with an injured wrist and now may be sidelined well into March or longer.
