The NFL Network is working on providing viewers a goal-line shot of the action.
The network is planning to put tiny cameras in the pylons on each side of the field to provide a bird's-eye view of scoring plays. The cameras could be installed and ready to go in time for the Chicago Bears-Green Bay Packers game on Thursday night.
Having a shot of the goal could aid referees in determining whether the plane is broken or when a runner's knee hits the ground.
“We've added a couple extra cameras in a couple of spots,” said Mark Quenzel, NFL Network senior vice president of production and programming. “I don't know if we're going to have it this week. We're still working out some kinks on the pylons that allow us to see goal-line stands, those types of things, and we're going to add a couple of cameras for isolating players.”
