Johnson (neck) was listed as a limited practice participant on Wednesday's injury report, Dan Salomone of the Giants' official site reports.
Johnson caught two of three passes for 35 yards during the Giants' 27-27 tie against the Commanders in Week 5, but he may have tweaked his neck at some point during the game. He would avoid an injury tag for Sunday's contest against the Saints if he can log a full practice in one of the next two days of practice.
