Bryan was forced to retire in 2016 after a series of concussions took a huge toll on his health but shocked the world when he got cleared to wrestle again last April at WrestleMania 34.
Cena was very happy to see the four-time world champion return to action as they both share the same passion for the business.
The Champ added that this is also great for the company as that means he will also attract an even larger audience.
Cena told Sports Illustrated: “Speaking from a co-worker’s standpoint, it’s great to have him back because he is very good at what he does.
“Speaking from a company standpoint, it is great to have him back because he is very good at what he does and audiences will show up to see him.
“Speaking from a personal standpoint on what I know about Bryan Danielson, I know that he is dedicated to wrestling and loves wrestling.
“He was so heartbroken when it was taken away from him before it was his decision to give it up. I can’t tell you how happy I am for him to go out there again and live his dream.
“He gives wrestling his all, and it’s great that he now has the outlet again where it can give something back to him.”
Bryan is set for action this Sunday at Extreme Rules where he will team up with Kane to take on The Bludgeon Brothers for the Smackdown Tag Team Championships at the PPG Paints Arena in Pittsburgh, Pennsylvania.
Cena’s next in-ring appearance will take place at WWE Super Show-Down on October 6 at the Melbourne Cricket Ground in Australia.
