General manager Doug Wilson announced the move on Saturday. It came one day after McCarthy scored his first goal since 2010 to help the Sharks beat Columbus 3-2 in their final game before the nearly three-week break.
McCarthy has one goal and one assist in 36 games with San Jose this season.
I don't have a crystal ball. Predicting is a real complicated thing. If we stay healthy, have enough depth and get the good goaltending we think we're going to have, you can go all the way.
