The Pittsburgh Penguins will once again try and eliminate the New York Rangers from the Stanley Cup Playoffs, but they'll be without the biggest part of their team yet again. 

You've no doubt seen the video footage by now of New York Rangers defenseman Jacob Trouba's questionable hit on Penguins captain Sidney Crosby during Game 5 of their Round 1 Stanley Cup Playoffs series. Crosby didn't return to the rest of the game, a Rangers victory that forced Game 6 back at PPG Paints Arena tonight. 

Crosby won't be suiting up as he continues to deal with the effects of the "upper body" injury he suffered as a result of the hit. The NHL decided against any fine or additional discipline for Trouba, as they felt there wasn't any ill intent on his part. 

But now, the worst has been confirmed for Crosby - he's once again dealing with a concussion.

This isn't the first time that the future Hall of Famer has dealt with a concussion. 108 career regular-season games and a playoff game in his career due to at least three previous instances in which he suffered the injury, with the most infamous perhaps being as he was knocked from the 2011 Winter Classic by then-Capitals forward David Steckel. 

Crosby has two goals and seven assists in the five games that he's appeared in during this year's postseason.
