In his fifth pro season, Lewis originally signed with the Saints as an undrafted free agent out of Northern Illinois in 2016. He spent his first three seasons with New Orleans before joining the Lions in the 2019 offseason. After Detroit cut him last August, Lewis went to the XFL, where he played for the Dallas Renegades. He re-signed with the Saints in mid-March, but the club cut him earlier this month.
Lewis, quarterback Teddy Bridgewater and offensive coordinator Joe Brady were all with the Saints in 2018. That year, Lewis was the target for the infamous non-call for pass interference against the Rams in the NFC Championship Game.
In 34 career games, Lewis has 20 receptions for 252 yards and two touchdowns.
