"Tough Enough" competitor Tanner Saraceno got coldcocked in Kuwait last week -- and the video of his brutal knockdown ain't pretty!

Saraceno was fighting for GFC MMA against Eldar Eldarov on Friday ... when Tanner took a stiff punch to the face that knocked him to the ground -- much to the crowd's enjoyment.

Following the fight, Tanner tweeted saying he was unhappy with the second round submission loss ... but had some big news coming in the next few weeks.

Unclear what he was teasing, but Tanner might have been a little loopy after this punch to the face.

Watch and enjoy.
