The decision didn't sit well with Jey's dad, Rikishi, who heavily criticized the decision.Speaking on the Off The Top podcast, Rikishi had this to say:"We all know that's got to be nothing but the bag. Is Goldberg able to give that type of a match to justify the Heavyweight belt? I mean, this belt has prestige on it, right? How do we get the belt back to Jey, and then we say, 'Okay, we're going to get Goldberg? Let's go get Goldberg; you're next.' And then he comes through. I don't know, man. Either somebody's taking too much Tylenol PM, that's writing this s**t, or you need to stay off the d**m Tylenol PM," Jey Uso will look to regain the World Heavyweight Championship this weekend.
