Chicago BlackHawks vs Boston Bruins Watch Online Live Streaming Stanley Cup Finals from Boston at 8:00 PM ET

Tuukka Rask, the Boston Bruins goalie, stopped 28 shots from the Chicago Blackhawks to help the Bruins win 2-0 on Monday night and move two wins from their second Stanley Cup title in three seasons.Game 4 is Wednesday night in Boston before the series returns to Chicago for a fifth game.

Injuries and the secrecy surrounding them have become part of this Stanley Cup story.  Chicago Blackhawks coach Joel Quenneville didn't want to talk about the injury that forced him to scratch forward Marian Hossa from the Stanley Cup finals against the Boston Bruins, according to espn.com.

And why not?

"I think that's self-explanatory," Quenneville said, once again declining to explain the secrecy that is as much a part of the NHL culture as playoff beards and Zambonis.

Hossa's surprise scratch from Game 3 and the one-word explanation -- "upper" -- for the part of his body that was injured is part of a long-running cat-and-mouse game NHL teams play. The theory goes that any revealing information about injuries could become a competitive disadvantage, reported espn.

Hossa is expected to play in Game 4, Quenneville said Tuesday, but only after making it clear that "I'm not going to get (into) exactly what the injury is or where it occurred."

"It's sort of a secret society in the hockey world and in the injury world," Blackhawks forward Dave Bolland said. "You don't want other teams having any injury information at all."

Hossa's mysterious injury may have been a turning point in Game 3, but it's hardly unusual in the secretive world of hockey injuries. Players and coaches say they just don't talk about what's hurting, partly because they don't want to seem weak in a sport where they hit each other for a living.

But mostly they don't want let the other team know where to aim.

"If I'm going out to battle and I have an injury to any part of my body, I don't want the other side to know what it is," Bruins forward Shawn Thornton said.

"There's times where you have to protect your players, and I understand it. I know it's frustrating for you guys as media. You're trying to share that information. The most important thing for us, we can take the heat for that, is protecting your players."

So, how to tell if an injury is minor? When a team actually admits it exists.

During the playoffs, information is even more scarce.

"It's that time of year where everybody's kind of battling. I would say that not just injuries, strategy, all that kind of information we're not going to talk about," Black Hawks forward Patrick Sharp said. "It's all part of being this close to the ultimate goal."

And does he have any injuries he cares to mention?

"No comment."
