As soon as AJ Styles appeared on Monday Night RAW during the Superstar Shake-Up, fans immediately knew that a big-name would jump ship the following night on SmackDown LIVE.

As we know, that name turned out to be arguably the biggest name in all of WWE - Roman Reigns.

SHAKE-UP

After taking out both Vince McMahon and fellow blue brand newcomer Elias, Reigns' focus is going to shift to a house show on Sunday night.

The WWE has booked The Big Dog, Seth Rollins and Dean Ambrose in a six-man tag team match, where they'll take on Baron Corbin, Bobby Lashley and Drew McIntyre in a match billed as The Shield's final chapter.

Once the contest is in the books, life will be different for Rollins as the Universal Champion on the red brand while Reigns will have his work cut out for him on SmackDown LIVE.

Eager fans have been looking ahead to see what the WWE has planned for Reigns on SmackDown.

A big sign which all but confirms a feud is what the WWE house show schedule looks like.

Off the bat, it seems as if Elias will be the first feud but that doesn't seem to be the case entirely.

According to Wrestling Inc, some of the first post-Superstar Shake-Up advertisement for live events have been issues which give us an indication of what the plan is for Reigns.

THE BIG DOG VS. THE VIPER

As of this writing, the advertisements suggest that Reigns will battle Randy Orton on SmackDown LIVE. In addition to this, Reigns is also expected to battle Elias at certain house shows on the nights The Viper has off.

Orton hasn't really featured in the main event scene on SmackDown for quite some time, and any feud with Reigns instantly elevates it into a main event storyline.

The last time Orton and Reigns were featured in a singles storyline was back in 2014 when Reigns defeated Kane and the former Evolution member in a handicap match. Reigns then attacked the latter during Triple H's announcement to determine who would challenge John Cena for the WWE World Heavyweight Championship - the night which started Brock Lesnar's dominance.

During that feud, it was Reigns that got the better of Orton after defeating him at SummerSlam.

Now that Reigns has cemented SmackDown as the show to watch, and with the move to Fox looming, perhaps he can be the one to get Orton out of the slump many fans believe he's in.
