Court documents show the case was dismissed last week at both parties' request, with no one admitting fault.
Attorneys for both sides mentioned a confidential agreement reached outside of court in declining to comment Wednesday.
The woman had sued after jurors acquitted Cox of criminal charges alleging he sexually assaulted the woman at his apartment in 2010 after a night of partying. She remembered little of what happened but became pregnant, and prosecutors said DNA tests indicated Cox was the father.
Cox now plays for the San Francisco 49ers.
