Cena noted that Shannon "gets very little time at home" and must sanitize himself completely once he does return home in order to minimize the risk of spreading the coronavirus.
"Dr. Evan Shannon is unbelievably brave and selfless," Cena said. "Doc, from me to you, you're a real hero."
John Cena @JohnCena
Dr. Shannon, you are the real deal! Having men like you on the frontlines gives us all hope. On behalf of @WWE, thank you for your hard work and selflessness. Show your appreciation to the healthcare heroes in your community by making your own “jersey” for these #TheRealHeroes. https://t.co/WpQauKb86I
Cena's video was part of "The Real Heroes Project," which was launched as a collaborative effort by sports leagues across the country.
