Based on reports, WWE talent Braun Strowman is expected to be out of action for four to eight weeks to undergo a small surgical procedure to correct some issues with his elbow. The angle on Raw this week from the UK where Roman attacked Braun’s arm with a steel chair, was intended to write Braun off WWE TV.
Due to the surgery WWE will have to change bookings for the upcoming Extreme Rules and Great Balls of Fire PPV. Reigns vs. Strowman was the planned Extreme Rules main event, while Braun vs. Lesnar for the UNiversal Title was intended to be the Great Balls of Fury Main Event.
At this time there is no word on what changes WWE plans to do.
