UPDATE x 2: Last night it was reported that Sheamus and Sin Cara (Hunico) had some kind of altercation backstage at this week's TV tapings.
According to a source, the fight did not take pace at this week's TV tapings. The altercation reportedly took place a few weeks ago, and news just got out this week. Sources within WWE have stated that the altercation did take place, and that if the fight had not been broken up, it could have "gotten really bad" for Sheamus.
The two have reportedly cleared the air and all is now well. That is the reason for Sheamus' tweet last night.
UPDATE: Sheamus tweeted the following regarding reports that there was some sort of altercation between the two at this week's TV tapings:
Must be getting punchy. Don't remember being beaten up by Sin Cara backstage... It's just how Mexicans & we Irishmen hug it out fella ;)
