BRUINS: Bruins center Patrice Bergeron suffered a moderate concussion Tuesday night and there's no timetable for his return, general manager Peter Chiarelli announced Wednesday.
This is the fourth concussion Bergeron has suffered in his career.
"It's prescribed as 'moderate,' and I talked to him about an hour ago. He was in very good spirits," Chiarelli said. "He was out walking today. He was annoyed at it. He was emotional last night. I don't know when you'll see him again. You'll see him again, but I don't think you'll see him tomorrow. He sounded really good, and I told him we'll work together in getting him back."
During the second period of Boston's 3-2 win against the Senators on Tuesday night, Bergeron collided with Ottawa's Colin Greening and fell to the ice. Bergeron was slow to get to his feet before skating off the ice. He did not return.
TRADE DEADLINE: The Columbus Blue Jackets are making a push for the playoffs by acquiring Marian Gaborik. The Buffalo Sabres continue to retool by dealing captain Jason Pominville. And rookie of the year candidate Cory Conacher is heading to Ottawa.
These were among the notable players moved before the NHL trade deadline Wednesday.
Columbus completed three deals, including one acquiring Gaborik from the New York Rangers for three players. Columbus (15-14-7) sits 11th in a tightly packed race for the Western Conference's eighth and final playoff spot.
Buffalo completed its fourth trade in three weeks by trading Pominville to Minnesota in exchange for goalie Matt Hackett and forward Johan Larsson.
Conacher, second in the NHL rookie scoring race, was traded by Tampa Bay to Ottawa for goalie Ben Bishop.
