The Boston Bruins and general manager Don Sweeney made a couple of roster announcements on Thursday. 

The team has placed Brendan Gaunce, Paul Carey and Alex Petrovic on waivers. 

With Petrovic's name in the mix, that means the team has signed him to a contract after he went through training camp on a PTO. 

Both Carey and Gaunce should clear waivers and join the Providence training camp. 

More to come regarding Petrovic.
