Johnson (hamstring) was listed as a non-participant on Wednesday's practice estimation, Zack Rosenblatt of The Newark Star-Ledger reports.
Johnson has missed the last two games with a hamstring injury, and his status on Wednesday's injury report isn't encouraging for his Week 18 status. If he hopes to have a chance to play in Sunday's regular-season finale against Washington, he'll likely need to practice in some capacity Thursday or Friday.
