Cobb helped Jacob Fatu keep his championship by attacking LA Knight during the United States Championship Fatal 4-Way match. Cobb’s relationship with Solo Sikoa’s party was indicated by this unexpected appearance, which was planned under Sikoa’s direction.

The WWE renamed Jeff Cobb as JC Mateo, which was confirmed during Solo Sikoa’s opening segment and later reaffirmed during Mateo’s entrance for his bout against LA Knight, was made public on SmackDown. The fact that WWE registered a trademark for “JC Mateo” on May 10 suggests that this rebranding was planned strategically.
