The Boston Bruins took a 3-0 lead in their series against the Pittsburgh Penguins Wednesday night, the Associated Press reports. If they win again in their next game on Friday, the Bruins will claim the Eastern Conference title and advance to play for the Stanley Cup, which the team won in 2011.

Boston will have to play without Gregory Campbell, who broke his leg blocking a shot in Wednesday’s game:

While killing a penalty, Gregory Campbell of the Boston Bruins blocked a shot by Evgeni Malkin of the Pittsburgh Penguins in Game 3 of the Eastern Conference finals Wednesday night and somehow managed to keep skating for nearly a minute despite what clearly was blinding pain.

Bruins general manager Peter Chiarelli announced Thursday that Campbell will miss the rest of the playoffs, according to the Associated Press.

Whichever team wins this series will play the Western Conference champion, a title currently being contested by the Chicago Blackhawks and the Los Angeles Kings, who won the Stanley Cup last year. The two teams play again Thursday, but Los Angeles will be competing without their best defenseman:

Duncan Keith will sit out Thursday under a one-game suspension for high-sticking Los Angeles’ Jeff Carter. Keith hit Carter with a one-handed blow in the second period of the Kings’ 3-1 victory in Game 3, opening a 20-stitch gash on the star forward’s face and cracking three of his teeth. . .

Keith, whose ungloved hand was nearly slashed by Carter an instant earlier, got a double minor penalty for his high stick, but was allowed to stay in Game 3. Keith had a hearing with the NHL’s department of player safety Wednesday, but spent the day uneasily waiting for a decision.

In postseason play, Keith has scored 10 points for the Blackhawks and has spent more time on the ice than any of the team’s other players. Chicago has a 2-1 lead over the Kings in the series.
