A.J. Styles suffered what WWE officials called a minor ankle injury last night in his TLC main event with Dean Ambrose in Dallas, TX.
Styles did get medical attention in the ring after the show was over. He was also being attended to after the match.
Styles retained his WWE title over Ambrose due to interference from James Ellsworth, which was to set up a Styles vs. Ellsworth title match on tomorrow night's SmackDown tapings in Houston. Ellsworth's interference was framed as a strategic decision because he thinks he has Styles' number after getting three fluke wins over him.
It is not clear at this point how Styles' injury will play into the match, or if he will be able to wrestle, or be limited in the match since it would likely have been more of an angle than a serious main event style match, or his status as far as house shows since he's the key star of the brand right now.
