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.
