The Boston Bruins and general manager Don Sweeney announced a roster move on Wednesday. 

Ahead of tomorrow's season opener in Dallas against the Stars, the team has announced the call up of defenseman Urho Vaakanainen. 

It seems though that these moves were salary cap moves. 

Joe Haggerty of NBC reports that Vaakanainen won't be with the team in Dallas while Connor Clifton and Karson Kuhlman will be with the team on Thursday while the duo weren't listed on the roster.
