10 WWE Superstars Who Must Retire In 2017
7. Mark Henry
Mark Henry has had a great and varied run in the WWE; from his beloved 'Sexual Chocolate' gimmick back in the Attitude Era to his 'Hall of Pain' success as World Heavyweight Champion.
In recent years, however, Henry has been used primarily as essentially a glorified enhancement talent to get over the likes of Rusev and Sheamus. With Henry now 45 and clearly struggling with knee problems, he has no need to still be getting in the ring. After all, Henry has been an ambassador for WWE for a number of years now and he'll clearly be moved into a similar kind of backstage role once he does decide to call time on his in-ring career.
Perhaps the only issue for Henry would be that after his previous 'retirement' speech was such a great angle, people might not take him seriously when he states his intent to hang up his boots this time!
