After telling reporters earlier this month he would be focused primarily on “depth” moves, Boston Bruins General Manager Peter Chiarelli has changed course and is trying to add an impact player before Monday’s NHL trade deadline, league sources not directly tied to the negotiations told

The shift in emphasis is a result of injuries to key forwards Nathan Horton (concussion) and Rich Peverley (knee).

The Bruins could focus on forwards Ales HemskyMilan HejdukKyle Okposo and defensemen Lubomir VisnovskyJaroslav Spacek and Johnny Oduya

And even though the Bruins have plenty of room to work with one estimate has them $13.2 million under the salary cap  Chiarelli might be hesitant to pull the trigger on a deal for a short-term rental. He said Wednesday that prices were currently “through the roof.”

“Last year we talked about adding a couple more bodies and chemistry. We were fortunate to get a couple of players that had addition years on their contracts and fit into our two-way system. I can’t tell you those deals are out there (this year),” Chiarelli said in an interview on Boston sports radio station 98.5 The Sports Hub. “I would hope to add some depth and I can’t dismiss the bigger deals, but the prices for rental players are through the roof right now.

“We paid a good amount last year to get some payers in — I’m not saying we won’t this year — but they’re through the roof.”
