Former All-Pro wide receiver Mark Duper is the ninth living former NFL player to be diagnosed with signs of chronic traumatic encephalopathy, or CTE, a degenerative brain disease many scientists say is caused by head trauma and linked to depression and dementia. Duper told the ESPN program “Outside the Lines” he learned of his diagnosis Friday from researchers involved with the testing.
“It was shocking,” Duper told the program about his reaction to hearing that he had signs of CTE. “I hoped nothing was wrong. I’ve had memory things where I would go to the store and forget what I went for. And I have emotional swings and panic attacks.”
Duper caught 511 passes during his 11 seasons with the Dolphins, and holds the team record for career receiving yards with 8,869.
