Johnson was listed as probable for Detroit's Sunday regular-season finale in Green Bay. He has the second-most receiving yards (1,437) in the NFL and is tied for the most receiving touchdowns (15).
Delmas has missed the past four games with a knee injury and told MLive.com that he didn't expect to play against Green Bay.
Defensive tackle Nick Fairley, who has been hampered this week by an injured foot, was limited but is questionable for Sunday. Defensive tackle Corey Williams, who has missed the past two days of practice with a hip injury, didn't participate and also is questionable.
