Professional wrestling fans may be accustomed to sexual innuendo in the ring, but a Canadian satellite broadcaster said on Monday it never intended to give them an actual porn show.

Bell ExpressVu blamed human error for briefly transmitting X-rated material last Sunday to theatres in several Canadian cities immediately after the end of a scheduled pay-for-view broadcast of a World Wrestling Federation Entertainment event.

"The company sincerely regrets that this incident occurred and has taken the necessary action to ensure that it will never happen again by rewiring the switching facility," Bell ExpressVu said in a press release.
