Axelson a healthy scratch, could Allison be traded tonight?

I just tuned in the Bruins game and found 2nd line forward PJ Axelson a healthy scratch. Could this be a sign that a trade involving him and Jason Allison be going down tonight? I know there is an unwritten rule if a player to be traded he is either scrathed or benched if it happens during a game. It just doesnt make sense that he is scratched. If anything is announced during the game, I will come back and post it. If anyone hears anything on the Anaheim broadcast please post it.
