A late-February Sports Illustrated report documented the Dallas Mavericks' workplace culture, which was allegedly rife with sexual misconduct. The team's owner, Mark Cuban, denied knowledge of the problematic culture.

Now, Cuban is facing his own allegation of sexual misconduct—seven years after it first surfaced. A weekly alternative newspaper in Oregon, the Willamette Week of Portland, has published details of a 2011 sexual assault case. The report states prosecutors did not pursue the case because they did not believe there was sufficient evidence. The report was obtained through a public records request.

The woman claimed that while she was taking a photo with Cuban in a Portland nightclub, the business mogul reached inside her pants and sexually penetrated her.

Cuban wrote to the Associated Press Tuesday that the incident "didn't happen." He added to the Huffington Post Wednesday, "I'll just repeat very strongly that it didn't happen."

The woman went to police more than a week after the incident, but she immediately told her friend and boyfriend about it.

Prosecutors reportedly said the woman decided in the end not to pursue the allegation. Furthermore, they added, "There is no evidence to corroborate the complainant's statement and there is evidence contradicting the claim."

The woman, however, stood by her claim while speaking to the Willamette Week.

"I filed the report because what he did was wrong," she said. "I stand behind that report 1,000 percent."

The woman reportedly submitted photos to the police department that showed Cuban "stretching to reach his arm down" while the woman had a "look of surprise and strain."
