Doe, now 19, said she was 15 when Vick first had sex with her in January 2004 and the affair continued for almost two years. In court papers, she said that she was the teen involved when Vick was convicted of contributing to the delinquency of a minor.
The lawsuit had been scheduled to go to trial next week in Montgomery County. The plaintiff was seeking more than $6 million.
Vick was not drafted in 2006. He signed with the Miami Dolphins in 2007, where he was listed as the "emergency" quarterback.
His brother, Michael, who played for the Atlanta Falcons, is now serving a federal prison term for running a dog-fighting operation.
