According to Harrison in an interview in 2013 with Stone Cold Steve Austin he had been asked by Vince McMahon to use a strong style version of a headbutt which Harrison stated that McMahon had no clue how dangerous it was. Harrison stated "Vince wanted me to use a strong style version of a headbutt as my finisher but he clearly had no clue about how dangerous it was. I only ever performed it five times in my whole career and won every match with it but every time I used it, I ended up busting myself open and causing my opponent to have a minor concussion and that's why I don't want to use it. Both myself and my opponent end up with a bad injury as a result."
