Mississippi defensive lineman Chris Jones came down hard Sunday after finishing his attempt at the NFL Combine's 40-yard dash.

Jones started off strong, crashing down in the last seconds of the run. To observers, it appeared as though the football player had tripped:

However, replays revealed the truth: near the end of the dash, Jones's genitals came flying out of his shorts, forcing him to the ground in an attempt to cover them up.

Jones didn't appear too bothered by the event, though, as he quickly jumped up, joining his coach on the sideline with a smile on his face.
