TMZ doing what they do best, found John Cena and stuck a camera in his face for a brief interview.
When asked if concussions are an issue in wrestling, Cena says concussions are an issue in anything that involves contact. He added that he would be open to donating his brain to science, as he would be open to anything that could potentially help people in the future.
Cena was also asked about rumors about Justin Bieber wrestling in WWE, and Cena said it didn’t happen, but he would be open to facing Bieber or teaming up with him.
