CHARLOTTESVILLE – Eighteen days after he was told it was no longer safe for him to play the game he loved, Connor McCartin still looked the part of a football player.

McCartin, a 19-year-old junior, summoned memories of the two concussions he suffered playing high school football, as well as the two he’s received during his time with the Cavaliers.
