Newton's day ended after he scored a 2-point conversion run that cut Atlanta's lead to 34-18 early in the fourth quarter. Falcons linebacker Deion Jones laid a clean hit on Newton near the goal line. Derek Anderson took Newton's place and Newton never returned to the game. If he does have a concussion, he'll need to go through the league's protocol before returning to action. The Panthers play on Monday night in Week 5 so owners will certainly need to have a backup plan.
