Wide receiver Calvin Johnson didn’t finish practice on Sunday afternoon due to a jammed thumb.
“He’s the kind of guy we have to pull out of practice, he doesn’t want to stop, he wants to finish. Sometimes it’s best to take his helmet away from him and say, ‘Let’s let this thing rest,’’’ coach Jim Schwartz said.
  Johnson was bothered by jammed fingers last week, but kept on practicing.
“Unless I hear something different it’s just a little jam. ... When you come out here twice a day and you catch bullets from some of these quarterbacks, and you’ve got defensive backs banging on your hands, that comes with the territory for those guys,’’ Schwartz said.
