5 Inactive WWE superstars and when they're expected back on-screen 

#3. Randy Orton

Randy Orton underwent knee surgery last month

The Legend Killer has been one of the best-known faces in WWE for more than a decade, but Orton hasn't been seen on WWE TV in more than a month because he underwent knee surgery following his loss to Jeff Hardy at Backlash in May.

Orton underwent knee surgery last month and the most recent update was that The Viper had been spotted in Birmingham, Alabama where he was obviously undergoing rehab ahead of his return to the ring.

Orton's WWE schedule is much lighter than it was in his earlier career and it's thought that this will continue to be the case when he's cleared to return to action in the coming months.
