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.

After an unforgettable weekend that saw WWE stage Saturday Night's Main Event and Evolution, the company turns its attention to SummerSlam on August 2-3 at MetLife Stadium in East Rutherford, New Jersey.
