Overshadowing all of the in-ring action was what appeared to be a serious-looking knee injury to Seth Rollins, one of the most important and talented performers on WWE's roster.

Bill Goldberg waved goodbye to professional wrestling, but he might not be the only absent superstar after WWE Saturday Night's Main Event. Seth Rollins seemingly suffered a knee injury during his match with LA Knight, bringing an abrupt end to their match.

WWE returned to NBC and Peacock with the 40th edition of Saturday Night’s Main Event, highlighted by Goldberg’s final match — a slugfest against Gunther for the World Title. The show also featured a heated U.S. Title bout between brothers, built toward a SummerSlam showdown, and hyped Sunday’s all-women’s premium live event.
