Barack Obama concedes he would not allow a child of his to play professional football due to the potential risks involved - dangers that the US president compares to boxing and smoking.
Last summer the NFL agreed to pay a $765 million settlement to compensate former players who have sustained injuries while also covering the costs of medical exams and funding further research.
However, this amount has since been rejected by a federal judge amid fears the money will not be enough to cover players affected by concussion. US district judge Anita Brody believes the settlement may have to cover 20,000 ex-pros for over 60 years.
The issue of concussion has been one of the most discussed in the NFL over recent months following the initial ruling in August, and Obama has now weighed by reinforcing the hazards associated with the pro game.
Speaking to the New Yorker Obama said pro football is not a career path he would allow his children to follow, and insists those who do must realise the danger in which they will put themselves in.
"I would not let my son play pro football,” he said "But, I mean, you wrote a lot about boxing, right? We’re sort of in the same realm.”
Obama added: "At this point, there’s a little bit of caveat emptor
"These guys, they know what they’re doing. They know what they’re buying into. It is no longer a secret. It’s sort of the feeling I have about smokers, you know?”
