Penguins' Ruhwedel concussed by hit from Senators' Ryan

The Pittsburgh Penguins are down another defenseman.

Chad Ruhwedel suffered a concussion Friday during Game 4 against the Ottawa Senators and will be evaluated once the team returns home, head coach Mike Sullivan announced after the 3-2 win.

Ruhwedel was forced to leave the game after a hit by Bobby Ryan late in the first period and was unable to return.

Ruhwedel joins Kris Letang and Justin Schultz on the Penguins injured defenseman list.

Ryan, by the way, was not penalized on the play.
