Johnson caught his only target for six yards during Sunday's 37-21 loss to the Texans.
Johnson and Jamal Agnew each played only nine snaps despite the fact Trevor Lawrence attempted 51 passes with Jacksonville trailing 27-7 at halftime. Johnson was claimed off waivers by the Jags after being waived by the Chargers at roster cutdowns, and he's unlikely to find much relevance in the offense while top wideouts DJ Chark, Marvin Jones and Laviska Shenault remain healthy.
