Johnson has been dealing with a sprained right ankle and sat out of last Sunday's 17-3 victory over the Minnesota Vikings. He originally sprained his ankle on Sept. 21, but played on it for the next two games before re-aggravating it.
On Wednesday, Johnson said is still feeling lingering pain in his ankle and that he "wouldn't be surprised" if he misses his second straight game on Sunday.
On Monday, the Lions will head to London to play the Atlanta Falcons in Week 8. Johnson said he expects to make that trip whether he plays against New Orleans or not.
Lions tight end Eric Ebron tweaked his hamstring during Wednesday's practice and sat out on both Thursday and Friday. Detroit was also without running back Reggie Bush against the Vikings, but Bush said Sunday that he will "100 percent" play against the Saints.
