Review Question - QID 219832

A college football running back is tackled during the opening game of the season and sustains a hyperextension injury to his neck.

His symptoms persist beyond 10 minutes, and on further questioning, he notes that he had two similar episodes last season that resolved prior to him being put back into the game and no further workup. Which of the following is the best next step in management?
