That knee must really be bothering Lions wide receiver Calvin Johnson.
The Lions star wide out is active and playing despite missing practice all week, but sat out two plays on the Lions opening drive against the Jaguars.
Johnson said he took practice off to be as healthy as possible for the game, but we’re not sure how much the knee will limit him over the course of the game.
The Lions gained 22 yards on their first drive, but had to punt away. The Jaguars will start from their 13.
