Shocking scene at a high school track meet in Florida over the weekend ... when an athlete sucker punched a runner in the head during a race.
The incident went down at the Tohopekaliga Tiger Invitational in Kissimmee on Saturday ... when witnesses claim the athlete in a black uniform was standing on the track as the runner in white and red was circling around and leading the pack.
Witnesses say the runner in first place yelled at the athlete in black to move ... but when the next lap came around, the guy appeared to purposely get in the way of the runner by standing on the track.
