Balor took to Twitter this afternoon and announced the injury, and attached an x-ray photo with his tweet. He also noted that the "full story" will be revealed on tonight's NXT episode.
There's no word yet on how much time Balor will miss from the ring, but the usual recovery time for a broken jaw is 4-6 weeks.
Triple H announced after Sunday's "Takeover: 31" main event, which saw Balor retain over Kyle O'Reilly, that Balor was taken to a local hospital for x-rays on his jaw. WWE then announced that Balor was receiving CAT scans at the hospital, to check for potential facial fractures. It was also announced that O'Reilly suffered several broken teeth, and was being evaluated for further injuries.
Stay tuned for updates on Balor's status and remember to join us for live NXT coverage at 8pm ET. Below is his full tweet:
