Bashaud Breeland's arrest Tuesday nearly turned tragic ... terrifying video of the scene obtained by TMZ Sports shows the NFL player's face was within inches of a cop's drawn gun during the stop.
Breeland was detained at around 11 AM at a South Carolina gas station after a York County Sheriff's Office deputy says he saw the K.C. Chiefs player and 2 other men smoking weed.
The officer claims when he stopped Breeland for questioning ... the 28-year-old became combative -- and in new footage we obtained from the incident, you can see how the confrontation escalated in a hurry.
