Pro wrestler John 'Bad Bones' Klinger -- who competed in Westside Xtreme Wrestling and TNA, among other promotions -- passed away just days after his latest match in the ring. He was only 40.
wXw made the tragic announcement on Monday. Klinger's cause of death hasn't been disclosed.
"We wish his family and friends strength during this difficult time," the wrestling promotion said.
This heartbreaking turn of events comes after Klinger's fight on May 11 ... when he wrestled former WWE star Flash Morgan Webster for the Prime Time Wrestling event.
