Penguins lose one of their top defenseman after another big hit from Ottawa.

The Pittsburgh Penguins are hurting in Game 2 of the Eastern Conference Finals. 

Not only did the Penguins lose forward Bryan Rust after he was obliterated by a huge open ice hit from Ottawa Senators veteran defenseman Dion Phaneuf, but they've also lost a critical piece on the blue line. 

One of the pleasant surprises for Pittsburgh has been the emergence of Justin Schultz since being traded by the Edmonton Oilers, but it looks like he may have really hurt his arm in tonight's game. 

Schultz was driven hard into the boards by Senators center Mike Hoffman, and he immediately came up favoring the arm that appeared to adsorb most of the impact. Right now fans in Pittsburgh have to hope that this isn't going to be a long-term injury. 

Here's the hit.
