After Mr. Chung returned to the game for several plays, the Patriots' coaching staff observed behavior that warranted a sideline review and the Protocol was triggered. The UNC and team medical staff conducted a sideline evaluation, which per the Concussion Game Day Checklist required a review of the video from the earlier play. Mr. Chung was cleared by the UNC and team medical staff. Subsequently, as is standard practice, the player remained under close observation following the sideline exam. During halftime, Mr. Chung was re-evaluated by the Club's medical staff and the UNC and found to have potential concussion symptoms and therefore was ruled out for the remainder of the game. Mr. Chung had delayed development of concussions symptoms, which is not uncommon, and was removed as soon as that was recognized.
