Multiple sources have reported that Sidney Crosby’s mysterious “upper body injury” is officially a concussion. Coach Dan Bylsma said in his post-game that Crosby will miss one week and that he was symptom-free following the hit from David Steckel in the waning moments of the Winter Classic.

Bylsma had no comment when asked if Victor Hedman’s hit, a hit for which Hedman was assessed a boarding call in Pittsburgh’s 8-1 win over Tampa last night, caused the concussion.

Pensburgh has all of the latest news, including speculation that the Penguins may have let Crosby play with a concussion against Tampa last night.
