Goldberg is warning Brock Lesnar ... keep your freakin' elbows to yourself -- making it clear if Brock lets his arms go crazy in their upcoming WWE match, retaliation is a-comin'.
Of course, Brock left Randy Orton a bloody mess when they faced off at SummerSlam back in August -- when it appeared Lesnar caught him with a very real elbow to the face. It was brutal.
So, with Goldberg set to do battle with Brock at WWE Survivor Series on Nov. 20th -- we asked if he was concerned about suffering the same fate.
