Lions coach Jim Schwartz on Calvin Johnson's knee: "He was sore after the game but he’s been sore after practice. It’s too soon to really know if it was any worse."
It could be just coach-talk, or it could be the team is really concerned. It was assumed that Johnson came out of the week no worse off, and more snaps and targets were in his future. It's a situation to monitor as owners are eager to safely put their star WR back into lineups.
