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.
Obviously a lot happened in a short period of time. At the end of the day, considering everything I went through, I really felt close to my teammates and I really feel like what we accomplished, I know we didn't win it all. ... I'm really proud of how we got there and what we did once we got there.
