In Mayberry's first professional football game, the Falcons faced the rival New Orleans Saints in the Louisiana Superdome.
With the game tied 34–34 in sudden death overtime, Mayberry intercepted a hurried chest pass by Saints punter Russell Erxleben, who was forced to retrieve the ball at the goal line after a high snap by long snapper John Watson.
Mayberry caught the ball in stride at the 6-yard line and waltzed untouched into the end zone to give the Falcons a 40–34 victory, Atlanta's third consecutive win over New Orleans in which the Falcons scored the game-winning touchdown in the final seconds of regulation or overtime.
The loss ended up keeping the Saints from their first winning season, as they finished 8-8.
