'DWTS' Jodie Sweetin's Dancing Partner Goes Down with Brutal Nut Check

"Dancing With The Stars" pro Keo Motsepe is probably still recovering from getting his balls nearly crushed during rehearsals Thursday ... and it was all caught on tape!

Motsepe was in the middle of turning his partner Jodie Sweetin when her microphone pack got loose, started swinging and yanked the mic cord right where it hurts most.

Needless to say, Motsepe needed a timeout, but Jodie found a way to make things worse!
