The Bruins and center David Krejci have come to terms on a three-year-extension keeping the forward in Boston through the 2014-15 NHL season.

The deal is expected to cost the Bruins $5.25 million per season against the NHL’s salary cap, and the deal also includes a partial no trade clause that does not kick in until years two and three of the contract.

Krejci, who was drafted by the Bruins in the second round of the 2004 NHL entry draft, has gotten off to a very slow start this season. Krejci has totaled 13 points in 20 games this season including just four goals.

Krejci has been the subject of trade rumors as of late, most recently sending him to Anaheim for Ducks forward Bobby Ryan. The contract extension doesn’t kill the chances of Krejci being shipped out of town, but I’m not sure it doesn’t help much.

Despite the high cost, it’s a good move for the Bruins as they continue to lock up their core players for the foreseeable future.

It’s very likely that the idea of needing to perform well in a contract year was what was holding Krejci back, hopefully for the Bruins sake getting a deal out of the way will wake up Krejci and finally get him going.

Krejci and General Manager Peter Chiarelli are set to host a press conference this afternoon at the TD Garden to officially announce the deal.
