Though WWE has promised to give an update on Seth Rollins tonight on Raw, Rollins is not backstage at Raw, according to PWInsider.
Rollins has reportedly flown back to Birmingham, AL in the past 24 hours, where Dr. James Andrews, who performs many surgeries on WWE wrestlers, is located. Rollins was being checked out in Birmingham last week as well after he first injured his knee. PWInsider is speculating that a second trip may be an indication that he will be undergoing (or already underwent) surgery on his knee.
