WWE Referee Marc Harris (who has been on WWE TV for about 2 years) on twitter responded to people telling him he messed up on Raw during the AJ/Natalya finish.
Harris responded on his Twitter (@WWE_Ref_MarcH): "the submission was released before the tap out, so I could not stop the match until the submission was reapplied. Good ref'n"
"no mistakes,submission was released before the tap out,so it was reapplied til the tap out. A great ref would pick that up & I did"
"no problem, alot of "know it alls" think they know the rules but don't. That's why I'm a professional cause I'm one of the best."
