The San Jose Sharks have kept one of the premier free agents off the market, agreeing with defenseman Erik Karlsson on an eight-year deal for more than $11 million per season, according to multiple reports.

The deal makes Karlsson, 29, the league's highest paid defenseman, barely surpassing the eight-year, $88 million deal for the Kings' Drew Doughty.

The Sharks acquired the six-time All-Star and two-time Norris Trophy winner from the Senators in September. Since he re-signed with San Jose, Ottawa gets a second-round draft pick.

Karlsson had a down year offensively as injuries limited him to 54 games this past season. His three goals were the lowest of his career. His 45 points were the lowest since 2012-13, when he only played 17 games for Ottawa.

Karlsson had 62 points for the Senators last season, 71 the year before that and a career-high 82 in 2015-16.
