Former Junior Seau teammate Gary Plummer said he believes that the recently deceased star probably had “over 1,500 concussions,” according to the San Jose Mercury News.
"In the 1990s, I did a concussion seminar. They said a Grade 3 concussion meant you were knocked out, and a Grade 1 meant you were seeing stars after a hit, which made me burst out in laughter," Plummer told the paper.
"Junior played for 20 years. That's five concussions a game, easily. How many in his career then? That's over 1,500 concussions. I know that's startling, but I know it's true. I had over 1,000 in my 15 years. I felt the effects of it. I felt depression going on throughout my divorce. Junior went through it with his divorce."
Seau was found dead Wednesday in his home in Oceanside, CA of a gunshot wound. Police are reportedly investigating the death as a suicide, which has led some to speculate whether Seau had suffered from brain trauma during his historic NFL career. Over the course of his career he tallied 56.5 sacks, 18 interceptions, and 1,524 total tackles. He was a 12 time Pro Bowler and a 10 time All-Pro.
