Johnson caught three of his seven targets for 54 yards and a touchdown in Sunday's 31-30 overtime loss to the Lions.
Johnson had a strong Week 1, with Tyler Shough targeting the No. 1 tight end at the third-highest rate among Saints players. Only Chris Olave and Devaughn Vele saw more targets, but Johnson's 18.0 yards per reception were second only to Olave's 18.2.
