[WATCH] The Bloodline's member sends cryptic message ahead of WWE RAW

The Usos may be on the verge of getting booted out of The Bloodline. But first, Roman Reigns and Solo Sikoa will look to end Kevin Owens and Sami Zayn's reign as Undisputed WWE Tag Team Champions.

The Enforcer and Roman Reigns had a tense moment on SmackDown during an in-ring promo segment with Zayn and Owens this past Friday. This happened as Reigns was looking to leave the ring, being disgusted with The Usos sneaking in and attacking the tag champions, in turn disobeying the orders of The Head of the Table.

Ahead of Monday Night RAW, as Owens, Zayn, and a mystery partner to be revealed on the show take on Imperium, Solo Sikoa has shared a cryptic message on his social media:

"Blood in the water, the sharks come out," Sikoa wrote.

Whether this means a potential appearance on tonight's show, which is set to emanate from the GIANT Center in Hershey, Pennsylvania, remains to be seen. Solo Sikoa may be looking to weaken the tag champions on the go-home edition of WWE RAW with less than a week left for arguably the 30-year-old star's biggest match to date.

You can watch the video Sikoa shared on his Twitter page below:

With Paul Heyman's shenanigans lately, often pulling strings backstage, it won't be a surprise if Solo Sikoa makes a surprise appearance on WWE's flagship show tonight. Night of Champions is less than a week away, and the go-home edition of RAW ahead of the event is only a few hours away.

ECW Original discusses WWE Superstar's potential to dethrone Roman Reigns

Tommy Dreamer recently spoke highly of Solo Sikoa, drawing comparisons to Umaga. He also brought up the ultimate question of whether The Head of the Table's title reign is destined to end at the hands of fellow Bloodline member:

"If Solo is the heater, everybody should be afraid to piss off the heater. Just let him be him." Dreamer continued, "Solo isn't there yet, but Solo will be ready. I have gone on record and said I don't know who is the person to defeat Roman Reigns, but what if it was Solo? I think WWE could get him this hot. Like Umaga, Umaga was so hot that if he would have turned babyface, the sky would have been the limit."

Meanwhile, the latest word on the rumor mill is that both Gunther and Solo Sikoa are internally viewed as the top heels for the next 10 years.

Is WWE slowly building Solo Sikoa as the breakout star to finally end The Tribal Chief's historic title reign? Only time will tell. You can read more about Paul Heyman potentially betraying Roman Reigns to side with Solo Sikoa after recently showing interest in the latter here.
