Fantasy impact: Johnson lost what could have been a touchdown at one point, when a 20-yard completion and dive into the end zone was overturned on review. The rule that players must "complete the process" of a catch -- often called the Calvin Johnson Rule after a similar play a couple years ago -- cost Johnson and the Lions again, and took 20 yards and a score off of Johnson's game totals.
Johnson, though, ended the game with his second-lowest receiving total since the start of last season. Even if he had gotten that 20-yard completion, he still would have been limited to 57 yards. We'll see if it's a long-term problem, or if the Vikings just focused on him in this game and Bush's emergence will give Johnson his opportunities back.
