The Pittsburgh Penguins earned a comeback victory Sunday against the Columbus Blue Jackets, 3-2. However, not all of the news was good Sunday. Penguins defenseman Mike Matheson is out indefinitely after sustaining an injury in last Thursday's loss to the New Jersey Devils. Matheson is considered to be week-to-week with an undisclosed upper body injury.

It is not known exactly when during the game Matheson was hurt. He logged over 19 minutes of ice time, so logic dictates it would have been late in the game. For most of the season, Matheson has been paired with Chad Ruhwedel as the third defensive pairing. So, this isn't a lethal blow, but one that hits the depth of the team. Sunday marked the first game since mid-November that one of the top six defenseman missed a game.

Matheson had seven goals and 14 assists in 50 games played this season.

In his absence, Mark Friedman had been recalled from Wilkes-Barre/Scranton. He played in both Saturday's contest against the New York Rangers and on Sunday. They were his first NHL games in almost two months. Yet, Penguins goalie Tristan Jarry noted it didn't look like it.

“It looks like he hasn't missed a beat, so kudos to him,” said Jarry. Sidney Crosby and the Penguins are in a tight race for the Metropolitan Division crown.
