No one said anything about voiding his contract, although in some cases yeah they deserve that, case in point Nuke in Colorado, you know It's bad when even his teammates have had enough.
But Timmins doesn't deserve that, He should still get paid, just trade him if you can, and if you can't send him to the minors.
Just get his cap hit off the team he's not needed.
Even if he were healthy he wouldn't be needed because even if Hakanpaa can't play and his contract is voided there are still AT LEAST 6 guys ahead of Timmins
