Sheamus may be injured

Sheamus was advertised for the Australian tour WWE is currently on, having already run shows in Brisbane and Melbourne with Sydney still to come. However, he was replaced by King Barrett on the first two and isn't expected back before the tour finishes up with the third.

Why?

WWE hasn't commented on the matter but the man himself sent the following tweet earlier today indicating he may be injured:

If anyone's looking for me, I'm #UpOver. #WheresSheamus. #LickingMeWounds.

There are some rumors going around but nothing is confirmed other than the fact that he's out. Monday's Raw emanates from Everett, Washington and he's currently advertised for the show, so we'll likely get an update then.
