What’s crazier: Erik Karlsson is skating or Rihanna in a Senators sweater? (Puck Headlines)

Here are your Puck Headlines: a glorious collection of news and views collected from the greatest blogosphere in sports and the few, the proud, the mainstream hockey media.

• Here’s Rihanna rocking a Sens sweater at Greystone Manor. Come to think of it, Chris Neil might be the kinder, gentler Chris by comparison. [@RihannaDaily, via Sportsnet]

• Erik Karlsson is skating again for the Ottawa Senators, and Craig Anderson believes "it's not that far-fetched that he could play before the end of the regular season." How this affects Eugene Melnyk’s homicide investigation into Matt Cooke is anyone’s guess. [@Ian_Mendes]

• James Neal had a concussion and will miss at least the next three games for the Pittsburgh Penguins. [Penguins]

• The end of Ryan Miller and Thomas Vanek with the Buffalo Sabres this summer? Good times, Pegula. Good times. [Dave Davis]

• Might the New York Islanders leave for Brooklyn early? [NYI Point Blank]

• The Boston Bruins’ use of Tyler Seguin as a center was rather short-lived. [Boston.com]

• No Joffrey Lupul tonight for the Toronto Maple Leafs vs. the New York Rangers. [QMI]

• Randy Carlyle on the New York Rangers: “They’re a four-line club that’s going to come at you … We know they’re going to be aggressive. That’s the mantra of a Tortorella hockey club. They want to be in your face.” [NYDN]

• The Philadelphia Flyers signed goalie Steve Mason to a one-year, $1.5 million contract extension. Repeat: This man won a Calder. #AndrewRaycroft [Philly.com]

• On top of the reasons we stated earlier, Japers’ Rink adds even strength prowess to the reasons why Alex Ovechkin has turned his season around. [JR]

• Lamenting Miikka Kiprusoff’s season with the Calgary Flames: “Let’s clear something up about Kiprusoff. He’s not Patrick Roy or Dominik Hasek. He’s not even in the same class as Jean-Sebastien Giguere when it comes to the post-season. Kiprusoff was a key cog for the Flames in 2004, but since then, the Flames have yet to pass the first round. Not to say that Kiprusoff is what’s holding them back, but there seems to be some mis-understanding over what a star, veteran goaltender can provide.” [Backhand Shelf]

• New episode of New Van Fan! [PITB]

• Finally. the NHL Department of Player Safety continues its educational series with a look at hard hits vs. illegal hits. Or as Pat Kaleta calls them, “hits.”
