Brad Richards and coach John Tortorella commented on the injury to Callahan on Wednesday afternoon, via Blueshirts United. We start with Richards:

"Hopefully it's short-term and he comes back quickly," alternate captain Brad Richards said of Callahan's injury following practice at the MSG Training Center on Wednesday. "Obviously the mood around here is that we want him back as soon as possible. He's a big part of every part of the game—power play, penalty kill, and 5-on-5—but that being said we have to push on, it's part of the game. Hopefully he is back soon."

And now for Torts:

"Every team goes through injuries," explained head coach John Tortorella on Wednesday. "When you lose a top guy like (Callahan) that shuffles your lineup. But people get moved up and they get an opportunity. How the (dressing) room is conducted and how (the players) accept responsibility and accountability certainly does help when you do lose a player like this."

From Andrew Gross of The Record:

Ryan Callahan will undergo an MRI later today, possible results will be available before tomorrow.. It's his left shoulder.

Callahan actually scored what turned out to be the game-winning goal in the second period, and the Rangers beat the Philadelphia Flyers, 2-1. But the injury occurred in the third period while in a scrap with Max Talbot.

With the Flyers swarming the net, Callahan took issue with Talbot. The two dropped gloves and were about to exchange blows when Callahan instead dropped to the ice. Here's what it looked like:

It certainly doesn't look good for Callahan. And while the Rangers can't simply cave in if he misses time, he will surely be missed.

From Pat Leonard of the New York Daily News:

"He's our leader and it's tough to see him go off the ice like that," defenseman Marc Staal said. "I'm still not sure exactly what it is or how bad it is, but he didn't come back obviously. So for a guy like that not to come back, it must be pretty substantial."

Callahan plays on the Rangers' top power-play unit, their top penalty-killing unit and their second line. Without him for more than the final 15 minutes, the Rangers nearly self-destructed.

On the season, Callahan has two goals and is averaging 20:01 minutes of ice time per game. He is fresh off a 2011-12 season that saw him set career highs in goals scored (29) and total points (54), and expectations were high that he would improve on those marks this season.

Now, the hopes are that this injury will be only be a minor one, and that he'll only miss a limited amount of time. A lot of fingers will crossed in New York on Wednesday.
