Minnesota Wild defenseman Brent Burns has another concussion.

General manager Chuck Fletcher says Burns is out indefinitely. Burns was diagnosed Monday with the head injury, which also kept him out of the last quarter of last season.

Forwards Pierre-Marc Bouchard and Petr Sykora are also on the inactive list for Minnesota with concussions. The team believes Burns suffered the injury in a collision during last week’s game against Phoenix.

Burns has two goals and eight assists in 21 games this season, with a minus-11 rating.

The Wild host Boston on Wednesday.
