Wounded in the shoulder following the WWE Money in the Bank show in May, Rey Mysterio still managed to capture the United States title against Samoa Joe. Unfortunately for him, the injury is too great and he will not be able to defend his title.
Rey had to give up his US title at RAW on June 3, 2019. He showed up in the ring with a shoulder scarf and was interrupted by Samoa Joe. Joe suggested that he not lie in his ad and admit that he is the champion as his shoulders were not on the ground when he fell to MITB. Rey finally announced that he was giving up his title, and give it to Samoa Joe!
Joe accepted the offer and without any mercy, he applied his Coquina Clutch on Rey. Joe becomes, for the second time, champion of the United States, while it was the first title waiver by Rey throughout his career at WWE.
