Penguins coach on Ehrhoff: 'He's flatlined in his recovery'

The Pittsburgh Penguins used a three-goal second period to just barely get by the New York Rangers in Game 2 of their first-round playoff series and did so with a blue line missing defenseman Christian Ehrhoff, who has been sidelined with an upper-body injury.

It doesn't seem like he'll be back anytime soon either.

Penguins head coach Mike Johnston said the blue-liner will not skate today. 

"He hasn't been progressing ... he's flatlined in his recovery," reports NHL.com's Jim Cerny.

The Penguins - who are also missing Kris Letang, Derrick Pouliot and Olli Maatta on the blue line - have been forced to use the inexperienced Brian Dumoulin and Taylor Chorney in the series so far.
