The Lions were without Calvin Johnson at practice for the second consecutive day, according to the team's official website.
A knee injury has given Johnson some problems throughout this year. He missed the Green Bay game as a result and wasn't at full strength against the Browns.
With Johnson missing the two most crucial days of practice, his status will be closer to 50/50 for Sunday's game.
Defensive end Ziggy Ansah was also absent from practice on Thursday.
