Kane, who remains under investigation, has not been charged for the incident, which allegedly took place on Aug. 2 at his offseason home in Hamburg, New York. A grand jury hearing was recently postponed and reportedly rescheduled for later this month. Police have not revealed details of the case.
Kane on Thursday said he had "done nothing wrong" and that he expected to be absolved.
On Sunday, Kane said it was good to be at training camp to keep his mind off of the police investigation.
"It's nice to be around my teammates and playing hockey," Kane said. "When I'm on the ice, just trying to focus on that. It definitely takes your mind off things."
Sources told The Buffalo News that Kane's DNA was found on the accuser's fingernails and shoulders, but those sources said the DNA evidence could have occurred from casual contact. Analysis of evidence in a sexual assault investigation often goes beyond just DNA, and the lack of DNA evidence in the rape kit does not suggest that sexual assault did not happen.
The case has shadowed the Blackhawks for weeks as they prepare for a season that begins at home on Oct. 7.
Sources told the News that settlement talks were ongoing between the two sides, but Kane's attorney, Paul Cambria, had previously denied any settlement talks.
