Schwartz said Friday that Stafford and Johnson have made "a lot of progress" in recent weeks after injuring their right knees. They're listed as questionable for Sunday's game when the Lions (1-5) host the Rams (0-7).
Stafford has missed two games. Detroit had a bye last Sunday, giving the No. 1 pick in the NFL draft another week to recover.
Johnson has missed one game with his injury.
