Sweeney provided an update on a few of the team's impending free agents, including forward Sean Kuraly, who he has had "very, very good, healthy communication" with.
"We expect to see something done, hopefully, in the short term, but I don't have anything definitive," Sweeney said of the 25-year-old restricted free agent.
He also remains in talks with Rick Nash, who is set to become an unrestricted free agent after playing in 23 regular season and playoff games for the Bruins after being acquired at the trade deadline. The potential for his return partially hinges on the Kovalchuk decision.
"He's going to take some time to make what decision he wants to make, and time is on his side," said Sweeney. "He gets to make that. We've been open to looking at that. Obviously, we would close the door if we were fortunate enough to be able to sign Ilya, but again, you're kind of jockeying simultaneously, but we understand that he has options as well - or he will have options."
Another key player who would become a free agent on July 1 without a new contract is backup goaltender Anton Khudobin. Sweeney said that he is in talks with Khudobin with the hope of re-signing him.
"It's an area we have to fill," said Sweeney. "It's a need…we just haven't found a landing spot."
