Rey Mysterio and his son Dominick were involved in one of the most talked-about moments of Survivor Series on Sunday.With the Master of the 619 taking a beating at the hands of Brock Lesnar in a No Holds Barred match for the WWE Championship, his son rushed to the ring and attempted to throw in the towel.But that turned into a double beat-down of the Beast Incarnate, who took a pair of low-blows, weapon shots, a double 619 and a Frog Splash from each of the men - with Dominick surprising many with his athleticism in the ring.It proved to be insignificant though as Lesnar still ended up winning, but Mysterio was given another chance to win a title though just 24 hours later, along with three other Raw stars.With AJ Styles' original opponent for his U.S. Championship - Humberto Carrillo - being attacked by O.C. members Karl Anderson and Luke Gallows at ringside, the Phenomenal One was left without an opponent.Mysterio, Ricochet, Randy Orton and Drew McIntyre all stated their cases, but instead of Styles weasling his way out of defending his title, a Fatal Four-Way, number-one contenders match was created.Styles would wrestle the winner immediately after, and it was the beaten-up Mysterio who would surprisingly walk out the victor, executing a small package on Ricochet for the win.That meant Rey had a tall order against AJ, but the odds were evened somewhat when Gallows and Anderson were removed from ringside for interference.It didn't stop them returning to the ring later on when the referee had taken a fall, but Mysterio received back-up from an unlikely ally in Orton.

The Viper had been prevented his chance of winning earlier in the night from Styles' buddies, and he got rid of them before dropping the champion with an RKO, allowing Mysterio to hit a Splash and become U.S. Champion once again.

Dominick rushed to the ring to celebrate with his father, and let's hope this title reign goes a lot more smoothly than his first with the same belt earlier this year - which he didn't even get to defend after suffering a shoulder injury.
