Boyle is set to become an unrestricted free agent July 1, while Havlat's contract will be bought out, if the Sharks are unable to trade him.
In addition to those two months, TFP first reported on May 19 that the Sharks will explore the possibility of trading captain Joe Thornton, sniper Patrick Marleau and goalie Antti Niemi.
TFP also reported that the Sharks are looking to get younger between the pipes and are expected to trade Niemi before his contract expires at the end of the 2014-15 season.
Marleau and Thornton both have no-movement clauses in their contracts and would have to approve any trade the Sharks attempt to complete.
Marleau met with the Sharks on May 16 to discuss his future with the organization, where it is believed the topic of a potential trade was brought up.
According to multiple sources, TFP has learned that Thornton is not interested in waiving his no-movement clause, though Marleau may be more inclined to do so.
In 82 games with the Sharks this season, Marleau registered 33 goals and 37 assists for 70 points. The three-time NHL All-Star has scored 30 or more goals seven times in his career, and has scored between 20 and 30 goals five more times.
The 34-year-old would come quite costly, as the Sharks would require a young rising star as part of any package.
Wilson is currently in Toronto attending the NHL Draft Combine, which concludes this weekend. Trade talks are expected to pick up between now and the NHL Draft, which takes place June 27-28 in Philadelphia.
