The Wrestling Observer Newsletter is reporting thatTyson Kidd appeared to have suffered some sort of injury during his match Monday night against Samoa Joe, but nothing was confirmed at the time.
Kidd was indeed hurt in that match with Joe as he suffered a spinal cord injury. WWE is attempting to keep all injuries secretive, so there are no official details at press time and it appears to be another injury that nobody is supposed to talk about.
Kidd is hoping to be able to make a full recovery without having to undergo surgery. There is currently no timetable for his return.
