Injured Penguins showcase ugly looking lineup on Sunday.

The Pittsburgh Penguins have had their share of injury woes this season and, although a number of players appear to be getting closer to a return, it has exposed the team's relative lack of depth at the forward posiion.

On Sunday, three days before their upcoming matchup against the Arizona Coyotes on Tuesday, the Penguins hit the ice for their morning skate and that lack of depth was painfully evident. The Penguins' bottom 6 forwards featured a third line comprised of forwards whose best days are behind them as well as a fourth line comprised of forwards who likely wouldn't be in the National Hockey League except for the aforementioned host of injuries the Penguins are dealing with.

Here is how the Penguins lineup looked today:

Forwards:
Guentzel-Crosby-O'Connor
Smith-Malkin-Puustinen
Hinostroza-Eller-Carter
Harkins-Gruden-Johnstone

Defensemen:
Graves-Letang
Pettersson-Karlsson
Shea-Ludvig
Joseph-Ruhwedel

Although the situation looks dire for the Penguins, and it is, there was also a silver lining during today's morning skate. PO Joseph returned from his conditioning stint in the American Hockey League and Chad Ruhwedel was back on the ice for the Penguins as well.

Unfortunately it wasn't all good news with no update forthcoming on the once again injured Bryan Rust.
