Rumors of a trade were first reported when the goalie refused to attend the Cup champions' visit to the White House back in January.
Thomas has one-year remaining on his contract which pays him $3 million, though his cap hit is $5 million.
Although Thomas has only raised the possibility, the Bruins would still have Tuukka Rask, who is more than ready to take on the starting job in between the pipes.
In 59 games with the Bruins, Thomas registered a .920 save percentage and 2.36 goals-against-average.
