On Tuesday night, pro wrestling fans saw the conclusion of the WWE "Superstar Shakeup 2018" event as a number of "Raw" superstars joined "SmackDown Live." Just one night earlier, fans saw Jeff Hardy win the United States title from Jinder Mahal who was the first superstar to move to "Raw." Hardy became one of the newest members of the blue brand on Tuesday night. In addition, fans saw an injured superstar return to television.

Male superstars to 'SmackDown'

The new United States Champion Jeff Hardy will now be a part of "SmackDown Live." In addition, former NXT Champion samoa joe is a part of the roster.

Both Joe and Jeff had recently shown up on the "Raw" episode after "WrestleMania 34" as they made their returns to the roster following injuries.

Samoa Joe also challenged current "Raw" roster member Roman Reigns to a match at the "Backlash 2018" pay-per-view which appears like it is still on. The Miz, who also was announced as a new member of the "SmackDown" team, will be facing "Raw" superstar Seth Rollins in a rematch for the Intercontinental title.

Making his big return from injury to join the "SmackDown Live" roster was Big Cass.

Cass, also known as Colin Cassady, was sidelined for months with a serious leg injury he suffered during a Street Fight on "Raw" against Enzo Amore. He made his surprise appearance during the main event by leveling Daniel Bryan with a big boot just moments after Shinsuke Nakamura attacked Bryan's tag partner AJ Styles.

In addition to those moves, "SmackDown" also gained the services of former "Raw" tag team champions Sheamus and Cesaro, as well as R-Truth, Karl Anderson, and Luke Gallows.

Female superstars to 'SmackDown'

Fans saw the trio of Ruby Riott, Liv Morgan, and Sarah Logan show up on "Raw" as new members of the roster. On Tuesday, it was Paige's former stable, Absolution, which made the move to "SmackDown." That means Mandy Rose and Sonya Deville will now pick their battles with the likes of Charlotte Flair, Carmella, Becky Lynch, and Naomi.

Also joining the blue brand is Charlotte Flair's "WrestleMania 34" opponent Asuka. "The Empress of Tomorrow" came up short in her attempt to defeat Flair for the WWE "SmackDown" Women's title at the big pay-per-view and now that title belongs to Carmella who wisely cashed in her "MITB" contract a week ago on a vulnerable champ.

NXT stars join 'SmackDown'

There were a number of NXT call-ups during Tuesday's show as well. Former tag team champions Sanity all made their main roster debut, although Nikki Cross was not part of that move. The former NXT Champion Andrade Almas and his manager Zelina Vega are now part of the blue brand.

These newest NXT call-ups add to the other superstars who joined the roster last week.

Fans saw Billie Kay and Peyton Royce attack former women's champ Charlotte Flair which led to Carmella's cash-in. That means the "SmackDown" brand gained a grand total of seven new stars from the NXT roster.

Future matchups

The latest WWE "Superstar Shakeup 2018" roster results should set up some interesting scenarios for the future. However, one has to wonder what WWE is up to as they recently announced co-branded pay-per-view events which seem to take away the previous concept of each brand having different events.

Still, the potential matchups available on "SmackDown Live" now could see AJ Styles battling Samoa Joe and Daniel Bryan finally getting his hands on The Miz after all that trash talk. The future looks pretty interesting for the brand.
