Have Ward and Salido skewed low blow usage to the point where this is ok?

Casuals who think low blows are a valid technique for use against opponents need to attend a c0ck punching workshop delivered by this low blow maestro: Was that intentional? No Was khan given a chance to recover? Yes Did he take full advantage of it? No Did he asked for the fight to be stopped? Yes Have lowblows accidentally happened in past? Yes Do fighters tend to continue? More of often than not

He said that he was pissing blood? Can a doctor verify this? If not, I am going to call BS because he knew that he had zero chance, so he quit and took a nice pay day without getting seriously hurt. The fans are the ones who got ripped off. It doesn't look like he got hit in the balls, and he held crawford's head low so crawford hit him on his legs instead of his body. It was caused by khan, and wasn't even intentional by Crawford. Crawford was winning, so it does not make sense for crawford to intentionally do something like this.

That was low even by Ward standards. BUT and this is a massive but...no point was taken from Crawford and no warning given, however the ref understood it was low and would have probably taken a point if it happened again. Thing is, the fight was stopped because Khan wanted it stopped. No idea what the injury is and punches that low can affect many different aspects of the lower body, including blood vessels but Khan looked to want a way out. An unfortunate end to a decent enough scrap.
