This one is probably a little more expected than the others given that Riddle is relatively new to WWE in comparison to Roman Reigns and they've been somewhat separated by the brand split between RAW and SmackDown.

The two have only set foot inside the same ring twice. It took place once during the 30-man Royal Rumble match in 2020 and once during the Survivor Series match in 2019 that featured men's teams from RAW, SmackDown and NXT.

However, given that Riddle has spoken several times about wrestling Goldberg and Brock Lesnar, is currently teaming up with Randy Orton and is a former United States Champion, it seems like it's only a matter of time before the two men clash.

This seems even more likely when you consider that Riddle has been the most consistent and perhaps even the best wrestler on Monday Night RAW for the last few weeks now, proving he's certainly deserving of a world title match opportunity.
