This story was updated late Monday afternoon.

Finn Balor's crowning moment of winning the Universal title over Seth Rollins Sunday at WWE SummerSlam may be for naught as he was injured, believed to be suffered after he was power bombed into the barricade by Rollins.

The severity of the injury is unknown at this point as he's scheduled for an evaluation Monday at television, but his arm was in a sling post-show and there was fear he would need surgery.

ESPN's Arash Markazi tweeted Monday afternoon that an MRI showed a possible labrum tear, but the extent of the injury won't be known until he has a surgical consultation this week. He continued that surgery is needed, Balor could be out of action for 8-12 weeks.

If that is the case, it will require some major overhauls in creative plans as he was scheduled to headline all the Raw brand shows as the Universal Champion.

Of note, Balor appeared Monday morning with new WWE Women's Champion Charlotte on Good Morning America and was not wearing any type of sling.
