Doughty was investigated by Hermosa Beach police in connection with a sexual assault allegation on March 1, according to the Los Angeles Times.
The woman said she met Doughty at a bar, and the two ended up taking a cab to her home, where she claims he raped her.
Doughty says the sex was consensual.
The woman reported the incident the same day, but detectives say she has been less than cooperative.
When asked what punishment he should receive, she reportedly said, "I don't want him to win the Stanley Cup.
Doughty's attorney, Craig Renetzky, told the L.A. Times that although the case was technically under review, he expected it will be rejected.
Renetzky has a history of representing NHLers in legal matters, including Toronto Maple Leafs defenseman Mike Komisarek and former Kings assistant coach Mark Hardy.
The woman has hired attorney Gloria Allred to represent her.
Doughty was the second overall pick by the Kings in the 2008 draft.
The Canadian defenseman missed almost all of training camp before this season before signing an eight-year, $56-million deal that made him the team's highest-paid player by average annual value.
He had two goals and four assists during the Stanley Cup Final, along with goals against St. Louis and Phoenix en route to the championship series.
