For you city folk out there -- "mud boggin'" is basically when you take an off-road vehicle and race it through the mud. It's pretty awesome ... in a redneck sorta way.
Sugar Bear was boggin' his ATV at the time of the accident -- it's unclear if Sugar Bear broke any bones in the wreck ... but he was spotted rockin' a fresh pair of crutches outside of his Georgia home yesterday.
BTW -- nice pants.
Of course, an accident was bound to happen -- Sugar Bear and his buddies get up to some pretty insane ATV shenanigans ... just check this clip.
