Boston Bruins first line center David Krejci will miss four to six weeks with a partially torn MCL in his knee. He sustained the injury in Friday night's game in St. Louis.

It is a devasting blow to the B's who are trying to hold on to a wildcard playoff spot.

Krejci has played in just 38 games this season. He has 7 goals and 19 assists.

The Bruins host the Vancouver Canucks Tuesday night at 7pm and that game can be heard live on Sports Radio 92.9 The Ticket.
