The Usos - Jimmy and Jey Uso are back as a team on WWE SmackDown and they'll be up against The Bloodline's new version led by Solo Sikoa to provide backup to their Original Tribal Chief, Roman Reigns.
The reunion of one of the most decorated tag team champions in WWE history was also significant, as they caused a championship change in the final segment of last night's episode.

In the main event of the October 25 SmackDown episode, Motor City Machine Guns (Chris Sabin & Alex Shelley) defeated The Bloodline (Tama Tonga & Tonga Loa) (c) to win the WWE Tag Team Championship.
Interestingly, the match went down just after the MCMG defeated #DIY (Tommaso Ciampa & Johnny Gargano) to become the new Number-One Contenders for the WWE Tag Team Championships. Solo Sikoa confronted MCMG and lured them for the title match, right on the spot.
The Bloodline's Tama Tonga and Tonga Loa competed in the tag team match while Sikoa and Jacob Fatu interfered from outside. This led Jimmy Uso and Roman Reigns to come out at ringside and brawl with them.
In the ring, Tama and Tonga were about to utilize steel chairs in their favor when Jey Uso arrived at the scene and laid both of them out with a pair of superkicks.
Jey and Jimmy then reunited and hugged, as Roman looked on from the stage. MCMG took advantage of the situation and delivered their finisher Skull & Bones for the pin-fall win to become the new WWE Tag Team Champions.
This title win for MCMG comes just a week after they've joined the WWE main roster, last week on SmackDown. Now, they've won tag team gold in WWE, TNA, NJPW, and ROH to become one of the most dominant tag teams in professional wrestling.
As for The Usos, their reunion will further insinuate the slowly building feud between the new Bloodline vs. the OG Bloodline. Reports suggest that a WarGames Match between the two factions is scheduled for November's Survivor Series.
