Andy Dalton, the Cincinnati Bengals' starting quarterback from 2011 to 2019, made nine starts for the Dallas Cowboys in 2020 and six starts for the Chicago Bears in 2021.
He's made two starts this season for the New Orleans Saints as starter Jameis Winston deals with several fractures in his back.
If he makes his third start for the Saints on Sunday, it will come against the Bengals - and he'll face his former team for the third time with a third team in three seasons.
Dalton, who turns 35 later this month, signed a one-year deal with the Saints in March.
