Penguins' Rutger McGroarty: Dealing with concussion

McGroarty was diagnosed with a concussion and is out indefinitely, the team announced Wednesday.

As previously reported, the Penguins moved McGraoarty to injured reserve after he suffered an injury during Tuesday's practice. It's a significant blow for the young winger, who already missed the first 18 games of the season due to an upper-body injury and is poised for another lengthy stint on the sidelines.
