If no medical personnel are on the sports sideline, any
athlete showing
potential signs of concussion, such
as balance or motor incoordination (stumbles, slow / labored movements), disorientation or confusion, loss of memory, blank or vacant look or visible facial injury combined with any of these other symptoms, should be removed from play, barred from returning and referred for a formal evaluation by a qualified health care
professional.
It might sound harsh but,
as with any
professional artist or
athlete, being challenged can be an effective tool toward performing consistently at one's highest
potential.
