Josh Yohe of the Pittsburgh Tribune-Review tweeted today that Penguins’ defenseman Kris Letang has shown concussion-like symptoms as a result of a hit he took from Dallas Stars winger Eric Nystrom in the Penguins’ 4-3 victory last night.

It was also announced today that Nystrom would not be suspended by the NHL for the hit.

Letang also missed 21 games earlier in the season after he suffered a concussion on a hit from Max Pacioretty of the Montreal Canadiens.

Despite missing such an extended period of time, Letang played in the NHL all-star game for the second consecutive season, and has put up 31 points in 40 games this campaign.

Matt Niskanen, who saw his ice time effectively neutered upon Letang’s return, will likely be leaned upon on to fill the sudden void on the power play.

Make no mistake, if the Penguins truly entertain notions of reaching the Stanley Cup finals, Letang is an incredibly vital piece of the team’s puzzle.
