Hossa misses third period after injuring knee

BOSTON -- Penguins forward Marian Hossa, acquired at the trade deadline from the Atlanta Thrashers, injured his knee in his first game for Pittsburgh and sat out the third period of their 5-1 loss to the Boston Bruins.

Hossa, a five-time All-Star, lasted just 13 shifts before banging knees with Glen Murray in the second period and leaving the game.

"It was an accidental hit, knee-on-knee," said Hossa, who could miss about a week. "This is disappointing. I was trying to get comfortable with my linemates. But injuries happen, and this is the tough luck of the business we're in."

Hossa was acquired Tuesday along with forward Pascal Dupuis for forwards Colby Armstrong and Erik Christensen, a top prospect and a first-round draft pick.

Hossa has 26 goals and 30 assists in 60 games after tying for sixth in the NHL with 100 points last season.
