As noted everywhere on the site (here, here, and here mostly), we know very little about Daniel Bryan's neck injury outside of the fact that he does, in fact, have a neck injury and he will, in fact, be getting a procedure done on it this coming Thursday.
With that said, there are reports out regarding his situation.
First, we start with WWE.com and its kayfabed story on THE DEMON KANE attacking Bryan on Monday Night Raw last night (May 12, 2014) in Greenville, South Carolina.
Already facing neck surgery this Thursday to repair a lingering injury, WWE World Heavyweight Champion Daniel Bryan's path back to the ring was set back even further thanks to a sudden attack by the Demon Kane less than an hour after he revealed his condition to the WWE Universe.
This could have simply been a way to write him off of television while he deals with whatever issue he's having, so nothing big here but it was a report put out there by WWE.
Next we get to the Wrestling Observer reporting that WWE officials internally are worried that the surgery could reveal bigger issues are at play here but that won't be known until he goes under the knife on Thursday. The expectation right now, apparently, is that he will be out anywhere from six-to-eight weeks, with the hope that he'll return in time for the Money in the Bank pay-per-view (PPV) scheduled for June 29 in Boston.
There is no plan to strip him of the WWE world heavyweight title right now. However, it's important to note that things could obviously change on that front based on his surgery.
Finally, the Observer is also reporting the Sheamus heel turn that was already supposed to have happened on Raw when he won the U.S. title from Dean Ambrose is now being pushed back to compensate for Bryan's absence as a top babyface. That doesn't mean the heel turn won't happen, just that it won't happen until Bryan is back and healthy again.
That's all we know, or all that's being reported, about Bryan's injury right now. Stay tuned for any updates as they come in.
