A pro wrestler landed awkwardly on his neck during a match this weekend -- and to make matters worse, continued getting pummeled in the same area.
The athlete's stage name is Jack Cartwheel, and he was competing in the National Wrestling Alliances' NWA 75 event down in St. Louis on Sunday ... where he was battling Colby Corino for the promotion's World Junior Heavyweight Championship.
Everything seemed to be going just fine ... that is, until Jack stood up on the ropes in an attempted body slam -- which appears to have gone awry, based on the way he came down.
