Some of the independent wrestling shows get pretty wild. A lot more hardcore stuff happens that WWE wouldn't dream of doing these days.
I read the article and it said that the wrestler threw it on purpose because he was pissed off that the other wrestler was hitting him too hard with the chair shots. Bet there will be some real heat between these two now next time they are backstage.
There have been many occasions over the years where wrestlers have legit hurt/injured and even try kill eachother on purpose.
I remember NewJack tried to kill Vic Grimes in a match after Vic Grimes in a previous match injured NewJack badly after botching a high risk move which end with NewJack falling from a high spot with Vic Grimes landing on top of him on a cement floor. It fractured NewJacks Skull and blinded him in one eye.
Their beef then start heating up cuz Vic Grimes was telling people backstage that he hurt NewJack on purpose and bragged about it. So NewJack once he was able to wrestle again had a match with Vic Grimes and they were like 20ft above the ring fighting on some scaffolding with a bunch of tables set up inside the ring to help brake the fall that was meant to happen when NewJack was to throw Vic Grimes off the scaffolding. NewJack decided fuck that and gave Vic Grimes an extra push and throw him away from the middle tables and more towards the turnbuckle and post. Vic Grimes ended up hitting a couple of tables but snapped his leg on the corner post.
NewJack came out and said in a documentary that he was trying to kill him and deliberately aimed at the corner post. He stated he was pissed off that Vic didn't fully hit the corner post.
Also, NewJack is a complete mental case. The guy is legit crazy and doesn't give a fuck bout nothing.
