There is a positive injury update when it comes to Rey Mysterio. Mysterio suffered a shoulder injury, due to which he had to relinquish the WWE United States Championship. As a result, he has not been seen on WWE TV since after being attacked by Joe following relinquishing the title.
However, the most recent update on his injury states that he is expected to make a return sooner than later. For now, they are targeting the 8th of July episode of WWE RAW for Mysterio to make his return.
When he does return, it will be interesting to see if he resumes his feud with Joe, or goes for the new United States Champion Ricochet.
