Report: Penguins' Kris Letang out indefinitely

Pittsburgh Penguins defender Kris Letang will be out indefinitely, according to a report from Sportsnet's John Shannon.

Letang, 27, sustained his injuries – he reportedly experienced concussion symptoms on Tuesday night, and dealt with a stiff neck on Wednesday – when he was hit by Philadelphia Flyers forward Zac Rinaldo from behind on Tuesday night.

The skilled defender, who has nine goals and 32 points this season, missed 26 games with a head injury during the 2011-12 season.
