#3 Kevin Owens
The former Universal Champion has been out of action for the past few months after sustaining injuries on both of his knees and had to undergo surgery. Recovering from double knee surgery is never an easy job, but Kevin Owens has made his time away from the ring as a blessing in disguise.
You can ask what good can happen to a person who just had surgery on both of his knees? Take a good look at this, and you'll see the answer for yourself. Quite a remarkable feat isn't it? Owens was always struggling to shed some pounds and has been in hot waters with Vince McMahon due to his physique affecting his in-ring work.
WWE aired a vignette on the December 17th episode of Raw announcing Kevin Owens' return to the ring. That could happen at the Royal Rumble with Owens entering the match as a surprise entrant.
