Finn Balor revealed on Twitter that he underwent shoulder surgery earlier today. No word yet on an updated prognosis but at last word he was expected to be out of action for 4-6 months.

As noted, Balor was forced to relinquish the WWE Universal Title on last night's RAW, just one night after winning it at SummerSlam. Balor suffered the shoulder injury while taking a powerbomb into the barrier from Seth Rollins.

Balor tweeted this photo from surgery today:
