Tyson Kidd, one third of the former Hart Dynasty alliance, won three tag team titles in his WWE career. He, David Hart Smith, and Natalya (his real life wife) were one of the more enjoyable factions to watch.
Sadly, it appears as though Kidd's career is over for good, according to Corey Jacobs from Wrestling News. Kidd suffered a severe (and nearly fatal) spine injury during a dark match against Samoa Joe on Raw last year. Joe botched his Muscle Buster finisher and it put Kidd's life at risk.
Kidd has said his neck and head haven't fully healed. We sincerely wish the best in him fully recovering, but staying away from the ring for life may be his best option.
