Documents filed Monday in U.S. District Court in Phoenix state that a settlement agreement should be finalized in 10 days. Details weren't disclosed.
The woman sued Winston in September and had been seeking $75,000 in damages.
She alleged Winston grabbed her crotch while they were waiting in the drive-thru of a Mexican restaurant in Scottsdale in March 2016.
Winston, the 2013 Heisman Trophy winner while at Florida State, was in Arizona for a charity event at the time.
After an eight-month investigation into the incident, the NFL in June suspended Winston for three games for violating the league's personal-conduct policy.
