MIAMI -

After years of hard hits on the field, legendary Miami Dolphins wide receiver Mark Duper is the latest living pro player to be diagnosed with signs of chronic traumatic encephalopathy.

Also known as CTE, the degenerative brain disease is caused by head trauma and linked to dementia and depression.

While signing autographs Saturday afternoon for fans at the Gridiron Grilloff in Pompano Beach, 54-year-old Duper said the diagnosis Friday was shocking.

"It's kind of scary to know that something's physically wrong with you," Duper said.

Another football star diagnosed this week with signs of CTE is hall-of-famer Tony Dorsett, who told ESPN's Outside the Lines he has experienced memory loss and depression.

"This is a rough game," Duper said. "A tough game. And we played rough and tough, and the NFL is trying to do something about it now because a change in the rules."

Although there is no known cure for CTE, Duper said he plans on living his life to its fullest. He said he no regrets about his career as an NFL player.

"I think football is a beautiful game. I mean, I made a living playing football, and if I had to do it again, I would do it again," Duper said.
