After months and months of speculation, Erik Karlsson is reportedly on the move.

According to Pierre LeBrun, the Ottawa Senators have dealt the superstar defenceman and Norris Trophy winner to the San Jose Sharks.

There has been no solid information on what the return package — rumored to include prospects and picks — might be to Ottawa as of Thursday afternoon.

The Sens and Sharks have had some history on the trade front this year, when Mike Hoffman was traded there earlier (and subsequently shipped off to Florida).

Karlsson, who has one year left on a seven-year, $45.5 million contract and is eligible to sign an extension with San Jose if he so chooses. Earlier this year, there was a deal in place with Vegas, which would have included Bobby Ryan and his albatross of a contract, which fell through at the deadline. Tampa was also said to be in the mix for a deal, but that died on the vine too.

The two-time Norris winner had 62 points in 71 games last season and was an uncharacteristic -25.
