Jeff Carter lost teeth. The Blackhawks lost Keith.

This is the second Carter trade the Kings have won. It goes without saying that Keith and Carter's Game 3 exchange resulted in a much bigger loss for Chicago, and not just because Carter says he technically only lost parts of his teeth.

“I chipped one tooth, cracked a couple on the bottom, but didn’t actually lose any,” he explained.

You can play through that. Heck, playing through lost teeth is pretty much the most hockey thing there is. Playing through lost lynchpins is another matter, and that's what the Chicago Blackhawks have to do Thursday night in Game 4. Duncan Keith is the engine of the Blackhawks' entire system. Like the bits of tooth and flesh he inadvertently hacked out of Jeff Carter's face that led to his one-game suspension, he'll be sorely missed.

The Kings, who are looking to go 9-0 at home in these playoffs and, in so doing, send the Western Conference Final back to Chicago tied at two games apiece, are acting like Keith's absence isn't a big deal.

"Chicago's the best team in the league this year, not based on one player," Kings head coach Darryl Sutter said prior to the game. "In fact, Duncan Keith's minutes were cut back substantially this year to allow them to be a fresh team every night."

He's got a point. Keith may be the star of the group, but the Blackhawks' defensive corps thrives as a unit.

The Boston Bruins' big Game 3 win over the Pittsburgh Penguins was not without a big loss. Gregory Campbell, one of the key members of a penalty kill that's been flawless in the Eastern Conference Final, broke his leg blocking a shot midway through the second. He's out indefinitely.

But before he left the game, Campbell spent nearly a full minute giving his team an emotional boost, fighting through the pain and remaining in the shooting lane as the Penguins pressed for the go-ahead goal. For some, this was evidence of the bravery and toughness of hockey players (not to mention the entire city of Boston, in the perhaps a tad over-the-top Bauer ad above). For others, it seemed strange to praise an athlete ignoring his body's dire need for medical attention. (That's been something of a problem in recent years.)

This is the moment that led to the #ImGregoryCampbell hashtag on Twitter, where hockey fans shared small moments of perseverance, many of which were badass on first glance, and kind of stupid on second thought. "I once broke my foot during 2nd grade recess but walked all the way back to class for story time," wrote Adam Summers. "I'm Gregory Campbell."

"I don't wash grapes before I eat them," tweeted James Walker. "I'm Gregory Campbell."

Eventually, even the Dallas Stars' official Twitter account got into it. And when they did, they won the whole freaking hashtag in a walk.

Had Sean Avery on our team. #ImGregoryCampbell

That's a bona fide zinger. There's something different about you these days, Dallas Stars. Beyond the logo.

UPDATE: Sean Avery caught wind of the zinger, and he's fired back appropriately.

@dallasstars did i ever say #ThankU for the 16 Million........hahahhahahaha

Yow. Tie game.

Anyway. Check out a collection of runners-up to the #ImGregoryCampbell crown here, or after the jump:

During playoff time, it's not unusual for a local radio station or a random fan to put together an "official" anthem for their team. Usually, it's to the beat of a recent pop song, like "Thrift Shop" or a not-so-recent one, like what CTV Ottawa did earlier in the playoffs.

The defending Stanley Cup champion Los Angeles Kings are getting into the game, thanks to the music of The Goon Squad, with the song "We are Los Angeles." According to the Kings, "This is a song that captures the spirit of the LA Kings, their fan, and the city."

Have a listen:

The Goon Squad is made up of four local musicians who also happen to be Kings fans. So where did the idea come from to write an them for the local hockey team? From a Q&A with the band on the Kings site:

GRANT: I've done a lot of touring in Europe, and have been around football fans as they cheer their teams on. Each city has a chant of musical theme that they sing, and it's always been pretty inspiring for me to watch. I've been a fan of the Kings for a long time, and got to thinking that, as a supporter, I really wanted the team to have a fight song... something to galvanize the crowd. It's also something I thought the city of LA could feel good about.

So that explains the European soccer vibe we got during the opening. And the Kings were right, we'll be singing this for hours because the repetitive chorus is now firmly stuck in our heads.

Pass or Fail: Los Angeles Kings "We Are Los Angeles" anthem.

By Chuck and Pants from What's Up, Ya Sieve?

We’re getting close to the end, and the biggest, baddest beards of this year’s playoffs are vying for their chance to reach the ultimate goal: full growth.

In this week’s BeardWatch, we give praise to the best of what’s still around in the Conference Championships, your current frontrunners for 2013 Playoff Beard of the Year.

Boston Bruins - Jaromir Jagr

When you’re tied for fifth all-time in playoff points, you can pretty much do whatever you want - including growing a beard like this.

The unconventional shape is clearly designed to distract us from the gray confluence on his chin, but it still makes him looks bad-ass. It’s so metal, we’re inspired to give it the devil horn salute. Add in the hair and #68 is ready to hit the road with the Spinal Tap Reunion Tour.

Jagr’s play has been strong and it was his tenacity against Malkin last night that led to Bergeron’s double-OT winner. If Bruins move on to the Finals, we’re pretty sure Jagr can crank this beard up past 11.

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.

• The Bruins are doing everything right. Their fans, on the other hand...

• Joel Quenneville would probably welcome a little more from Patrick Kane, sure. “It seems like the top guys, finding a way to score or be productive has been challenging. But I think if you’re contributing in other ways, the team game you can hang your hat on, it’s something you look for. That’s what we’re looking for and hopefully there’s some production along with it. [CSN Chicago]

• Duncan Keith's one-game suspension means intentional violence still gets a pass in the NHL. [Backhand Shelf]

• Did Keith get off easy? [Jewels From the Crown]

• Turns out Jeff Carter didn't actually lose any teeth after all. “Those were already gone,” he noted. “I had a tough practice in Chicago [when] my bridge fell out." On the slash, “I chipped one tooth, cracked a couple on the bottom, but didn’t actually lose any." [Frozen Royalty]

• "The simple fact is the Pens pissed away the early two games of this series with foolish mental mistakes, physical errors that ended up in their net and useless after-the-whistle scrums." [Pensburgh]

• Steve Ott expects more reckless stickwork with mandatory visors: “That’s where I think the biggest issue (is) falling in with the guys that don’t have one on,” Ott said. “ … When you don’t have a visor on, obviously you show a little bit more respect. You try not to bring your stick up or you wouldn’t have it up because it’s in the back of your mind.” [Buffalo Hockey Beat]

• With the World Hockey Championships coming to Belarus next year, Belarusian police officers are being trained to apologize to foreign hockey fans. [Ria Novosti]

Getty ImagesFrom Dec. 2010 to Feb. 2012, St. Louis Blues center Andy McDonald missed 74 games due to two concussions.

In an interview with Fox Sports Midwest after his second comeback, McDonald said, “There was a time when I thought I might not make it back with how poorly I felt. You just try and enjoy each moment and each game and realize how lucky you are to be playing in the NHL.”

On Thursday, McDonald’s health concerns finally trumped his NHL career.

As first reported by Andy Strickland of TrueHockey.com, McDonald, 35, has decided to retire from the NHL after 11 seasons due to post-concussion concerns.

From Strickland:

“The last few years too much of the focus became worrying about the next hit. I was always thinking about it.” Said McDonald.

Retirement began creeping into McDonald’s head during the regular season but it wasn’t until after the Blues were eliminated by the Los Angeles Kings did he become 100% sure. He spent the last several weeks with his family and is confident now is the right time to move on with his life.

“I’m fortunate to get out now. I know I could play two or three more years and I love the game of hockey, but healthwise I know I shouldn’t be playing.”

McDonald played seven seasons with the Mighty Ducks of Anaheim (and then the Anaheim Ducks) before being traded to the Blues in a package for Doug Weight in Dec. 2007. He won a Cup with the Ducks in 2007.

Why would a San Jose Sharks fan ever make a Stanley Cup Playoffs wager? Unless, like, it’s against the San Jose Sharks?

Alas, two Sharks fans decided to take a foolhardy bet that San Jose would defeat the defending champion Los Angeles Kings in the Western Conference semifinals. Well, to quote Noomi Rapace in another heavily hyped, aesthetically pleasing disappointment: “They aren't what we thought they were. I was wrong. We were so wrong.”

highrankwebsites.comPD reader Brian Beltz of High Rank Websites, Inc., a.k.a. the Sharks fan on the right, explains:

A couple of the guys in my office made a bet on the Sharks Kings series. The results are pretty funny and I thought you guys would get a kick out of it. Our office is pretty casual, we ended up documenting the whole process in – and I use the term loosely – a photo shoot.

The other guy is my co-worker, Brian Debelle. We work on the same team and felt confident in the Sharks prospects after they swept Vancouver. The bet was who ever lost had to get the Kings/Sharks Tattoo and share it on all of their social media (Debelle is a cowboy/manly man, so he was particularly shameful). His parents are not proud.

Their Twitter handles are @buckleyourbeltz and @thebriandebelle for further shaming.

While there would be nothing better than to see these gentleman forever linked by their ‘half-a-Kings-crest’ on their lower backs, the tattoos are just temporary. Their humbling embarrassment? Captured forever.

So, in summary: Stop making playoff bets, Sharks fans. You’re either going to end up with a temporary Kings back tattoo shared across the Internet or in a bunny suit dancing at Staples Center.
