WWE's worst fear has come true as Finn Bálor's title reign ends less than one day in

What a disaster.

WWE's worst fear has been confirmed, and Finn Bálor will be out for six months due to a torn labrum in his shoulder, per WWE.

The injury occurred during Sunday night's Summerslam match against Seth Rollins, per WWE.com:

"He hit the wall during the match, dislocated his shoulder and was able to put it back in himself in a split second," said ringside physician Dr. Chris Robinson. Bálor was able to finish the match, but Dr. Robinson noted that an MRI yielded results earlier today showing "a possible labrum tear."

Bálor's upset at WWE Summerslam handed him the first-ever WWE Universal title.

According to Wrestling Observer, there's a fear Bálor might have to undergo surgery and it could keep him out of action for an extended time, requiring a major shift in creative plans.

The injury comes at the most inopportune time, as he was enjoying a push directly to the top of the company after bouncing from NXT.

This isn't the first time a Seth Rollins power bomb has injured a WWE star.
