Query: What is it called when a ref is knocked out?
Context: In WWE, a referee must see the violation with their own eyes to rule that the match end in a disqualification (simply watching the video tape is not usually enough) and the referee's ruling is almost always final, although Dusty finishes (named after, and made famous by, Dusty Rhodes) will often result in the referee's decision being overturned. It is not uncommon for the referees themselves to get knocked out during a match, which is commonly referred to by the term "ref bump". While the referee remains "unconscious", wrestlers are free to violate rules until the referee is revived or replaced.
