Q. In layman's terms what is the NFL's concussion protocol?

A. This is from a recent Indianapolis Star story: Here are the steps in the NFL's Return to Practice Protocol:

Rest and recovery: The first step in his recovery will be rest until his signs and symptoms and neurologic examination, including cognitive and balance tests, return to baseline status. Neurological testing can be introduced at any point during the first three steps in the process.

Light aerobic exercise: This is conducted under the oversight of the team medical staff and can include cardio, stretching and balance training.

Continued aerobic exercise and strength training: These activities may mimic sport-specific activities.

Football-specific activities: These activities are non-contact and can include throwing, catching, running, etc.

Full football activity: Once the player has been cleared by the team physician and neurological consultant, he can participate in practice and games.

If a player exhibits reoccurring signs of the concussion during any point in the process, they return to the prior step.
