SummerSlam last weekend,
Roman Reigns was able to retain his Undisputed
WWE Universal Championship because of the interference from Solo Sikoa and Jimmy Uso.
Ahead of the show, the rules for the Tribal Combat match were made clear that there couldn't be interference, and the two men had to settle their differences alone.
This appeared to change since Reigns needed the help of two members of his family to finally defeat Jey Uso, and it could have been a last-minute decision. It was revealed after the show that Reigns suffered an injury in the opening stages of the match,
which appears to have been off the Suicide Dive to the outside.
