WWE SmackDown video highlights: Jey Uso defeats Solo Sikoa

Jey Uso has momentum on his side heading into SummerSlam.

In the main event of last night's SmackDown, Jey was victorious against his younger brother Solo Sikoa. To send a message to Roman Reigns, Jey hit a spear on Sikoa at the end of the match. Jey then followed up with a top rope splash to get the win.

Sikoa attacked Jey after the match in an attempt to prevent Jey from making it to SummerSlam. But Jey was able to fight off the attack and beat Sikoa down with a steel chair.

Jey is facing Reigns in a Tribal Combat match at tonight's pay-per-view. It's an anything goes match for the Undisputed WWE Universal Championship -- and Reigns' position as Head of the Table is also on the line. If Jey wins, he will become the new Tribal Chief.

Earlier in the show, Jey interrupted a segment with Paul Heyman. A fired up Jey said he's bringing everything he has to SummerSlam. Jey vowed that he's going to defeat Reigns.
