The Shield was a faction in WWE consisting of Roman Reigns, Seth Rollins, and Dean Ambrose. They were known for their brutal and aggressive style, often targeting high-profile wrestlers.
While they did have various feuds and confrontations with other wrestlers, The Rock was never a target of The Shield.
It's possible you may be thinking of a different event or confusing the Shield with another group. Could you please clarify what event you are referring to?
