Since this site is non-spoiler, I will not be listing any injuries that occurred at a pre-taped event until either the show airs or if the promotion lets the story out on their website prior to airing the program. This policy will also hold true for returns to the ring. If the return is a non-publicized surprise during a pre-taped event, I will not mention the return until the program airs.
RAW Brand Wrestlers on the D.L.
Alex Riley - Alex posted on his Twitter account that he had knee and elbow surgery in September. There is no timetable for his return.

Ricardo Rodriguez - Ricardo had his ankle broken by Jack Swagger in March. That injury is all part of an angle add fuel to the fire for the upcoming match at WrestleMania XXIX between Jack Swagger and Alberto Del Rio. It is not know when Ricardo will return to action from this "injury".
SmackDown Brand Wrestlers on the D.L.
Christian - In September, Christian appeared via satellite in a segment of SmackDown sporting a sling and claiming that he had shoulder surgery due to a Brogue Kick he received a year earlier. That explanation for his injury doesn't make storyline sense because he returned to the ring for several months after that kick and won the Intercontinental Championship. Despite the convoluted storyline explaining his absence, the injury is real and there is no timetable for his return.
