Many high-profile athletes have pledged to donate their brains posthumously for research in recent weeks and months, and WWE Superstar John Cena revealed he will consider adding his name to that list.

As seen in this video Wednesday, courtesy of TMZ Sports, the 15-time WWE world champion didn't commit to donating his brain, but he didn't rule it out, either:

"If I could do something after I exist to help the existence of mankind to come, yeah, I think I might," Cena said.

Former WWE and WCW world heavyweight champion Kevin Nash made the decision in March to eventually donate his brain to help with the future understanding of chronic traumatic encephalopathy, or CTE, per ESPN.com's Michael Rothstein. Shortly after Nash's announcement, former WWE world heavyweight titleholder Mick Foley likewise revealed he'd follow suit.

Both current TNA and former WWE star Jeff Hardy and former ECW and WWE standout Rob Van Dam are also among the big-name wrestlers to commit to the cause.

Despite the choreographed nature of professional wrestling, concussions are commonplace, much like they are in most other sports.

WWE Superstars are especially at risk due to their extensive schedules, which call for them to be on the road and work matches for the majority of the year.

It is unclear how many concussions Cena has suffered over the course of his career, but as a 14-year veteran in WWE who has been the face of the company for most of that time, he has been put in harm's way on a regular basis.

Although he remains polarizing, Cena is unquestionably one of the biggest names in the history of sports-entertainment, and he could inspire many to follow in his footsteps if he does ultimately donate his brain.

The idea already seems to be catching on significantly in wrestling circles, which is a huge positive when it comes to learning more about the dangers of the sport and protecting future participants.
