Patrick Kane is the subject of a police investigation in his offseason home of Hamburg, New York for sexual assault.
According to the newspaper's sources, who are in law enforcement, the woman went to a hospital, where a rape kit was administered.
Kane has not been charged.
Kane and Blackhawks captain Jonathan Toews agreed to matching eight-year, $84 million contracts last summer, and their deals go into effect during the 2015-16 season.
