Horrifying moment during the Citadel vs. Duke game on Monday ... Bulldogs head coach Duggar Baucom collapsed on the sideline and needed to be taken to the hospital.
It all went down at Cameron Indoor Stadium ... when just a few minutes into the first half, Baucom terrifyingly crashed to the floor.
You can see in video from the arena, trainers and players rushed to the 61-year-old, who was eventually helped off the court and taken to Duke University hospital, where he stayed overnight for further evaluation.
