Detroit Lions WR Calvin Johnson (head) briefly left the game Week 4 after taking a helmet-to-helmet hit during the game. It appeared he underwent a concussion test before returning to the game.

Our View: Johnson was mostly contained during the game by the resurgent Vikings secondary. The bye week is well-timed for Johnson and the reeling Lions.
