-- Plans for the men's Elimination Chamber match were changed recently as both Seth Rollins and Jason Jordan were originally supposed to be included as competitors.
-- Jordan's removal is obvious as he is suffering from a neck injury and recently underwent surgery while Rollins was pulled for unknown reasons. One possible reason is that Rollins was only in the match to work an angle with Jordan, leading to a WrestleMania match, but with Jordan out of the match, Rollins' participation was unmecessary.
-- As for Jordan's recovery and return date, it appears that WWE is still holding out hope that he can wrestle at WrestleMania against Rollins, but it is said to be far from a given.
