Count Justin Timberlake and Jessica Biel among the 48 percent of American parents who wouldn’t want their child to play football.

Addressing the media Thursday at an NFL news conference, the Super Bowl LII halftime performer said his 2-year-old son Silas won’t be suiting up in the near future.

“Uh, he will never play football. No, no,” Timberlake said.

The percentage of parents who would encourage their child to participate in a different sport instead of football is up eight percent since the same query was posed four years ago, according to a recently released NBC News/Wall Street Journal poll. The results also concluded 49 percent of Americans wouldn’t encourage children to engage in a different sport due to concussion concerns.

Timberlake, 37, added his primary concern with son Silas at the moment is manners.

“I mean, yeah, it’s kind of like that thing where my main objective is that he become a great person. And if he wants to get into the arts or sports, then yeah, I would fully support that. I think I can hopefully offer him some advice on what to do and what not to do, so yeah, but right now we’re working on our manners. That’s a big deal in our house right now. It’s like, one thing at a time,” the singer said.

Three retired NFL linebackers, Nick Buoniconti, Harry Carson and Phil Villapiano, recently issued a plea to parents to keep their children from participating in tackle football in hopes of protecting their brains from traumatic brain injuries. The trio advise flag football for kids under the age of 14.

Buoniconti, 77, was diagnosed with dementia and said he now regrets playing tackle football at 9 years old.

“I used to be eloquent as a speaker,” the Hall of Fame middle linebacker stated. “I can’t even tell you how I feel now.”

After examining 202 brains of deceased football players, neuropathologist Dr. Ann McKee found that of the 111 that played in the National Football League, 110 of those had chronic traumatic encephalopathy, better known as CTE, results which were published in the Journal of the American Medical Association last year.

Thirty-three percent of Americans believe the NFL has taken action to prevent and limit the number of concussions, according to the poll, two years after the league pledged $100 million to concussion research.
