A medical study released Tuesday found CTE in 99 percent of the brains of NFL players used in the research – a result that’s concerning for the Carolina PanthersThomas Davis.

Speaking to the media Wednesday, Davis called the findings “alarming.”

“I’d be lying if I said I wasn’t nervous,” Davis said, according to Joe Person of the Charlotte Observer.

As an NFL linebacker, collisions are part of the job description for Davis. He’s played the game for 12 seasons and racked up 939 career tackles. Still, the joy outweighs the pain for him.

“This game, I just love it so much,” Davis said, according to Jeff Darlington of ESPN.

CTE is a degenerative brain disease often found in athletes who have suffered repeated brain trauma. It can only be diagnosed after death.

Davis does allow his 13- and 9-year-old sons to play football and said he likes the way their coaches teach tackling, according to Person.
