The original Sling 'Em-Fling 'Em Wrestling Ring was recalled on November 4, 1991, due to 4 cases of children seriously injuring themselves falling on the corner ring posts. In one of those cases, a plastic ring post penetrated the child's body causing serious injury. The posts were made of hard plastic and would not budge much, if at all when fallen or stepped on. 1.4 million rings were sold. The rights to the ring were purchased by the toy company Jakks Pacific and it was re-released as The Monster Ring in the '90s. Protective caps were attached to the posts for added safety.
