Former Oakland Raiders quarterback Ken Stabler, the late league MVP and Super Bowl winner who is a finalist for the Pro Football Hall of Fame, has been diagnosed with the brain disease CTE, Boston University researchers said Wednesday.
Stabler, who died of colon cancer at 69 in July, had Stage 3 chronic traumatic encephalopathy, Dr. Ann McKee told the AP. McKee said the disease was spread throughout his brain, with ‘‘quite severe’’ damage to the regions involving learning, memory, and regulation of emotion.
‘‘We’ve now found CTE in former NFL players who played every position except kicker,’’ said McKee, a professor of neurology at BU. ‘‘While we know on average that certain positions experience more repetitive head impacts and are more likely at greater risk for CTE, no position is immune.’’
The disease, which can be diagnosed only after death, is linked to repeated brain trauma and associated with symptoms such as memory loss, depression, and progressive dementia. CTE has been found in the brains of dozens of former football players.
According to Chris Nowinski, the founder of the Concussion Legacy Foundation, Stabler told his family he wanted to have his brain studied after learning that former NFL linebacker Junior Seau had been diagnosed with the disease. In 2012, Seau shot himself in the chest at the age of 43.
‘‘What is interesting about Ken Stabler is that he anticipated his diagnosis years in advance,’’ Nowinski wrote in an e-mail to the AP. ‘‘And even though he’s a football icon, he began actively distancing himself from [the] game in his final years, expressing hope that his grandsons would choose not to play.’’
McKee said the extent of the damage to Stabler’s brain was surprising because he was relatively young when he died and because he was a quarterback and thought to be less exposed to repeated head trauma.
‘‘There was no evidence of any other brain disorder to explain the difficulties he experienced during life,’’ McKee said.
Stabler was the NFL’s Most Valuable Player in 1974 and led the Raiders to victory in the 1977 Super Bowl.
Promise is made
Titans owner Amy Adams Strunk promised she will do ‘‘everything in her power’’ to return the franchise to the success it enjoyed 15 years ago. Strunk wrote in a letter received by some season ticket-holders she has changed the team’s president, head coach, and general manager since taking over in March. She also said the Titans are not raising ticket prices for 2016. ‘‘I realize we have not met your expectations, and our recent on-field performance is unacceptable,’’ Strunk wrote. ‘‘My goal is simple: to return the Titans to the consistent playoff contender we were during our first several years in Nashville.’’ . . . The Jets hired former Colts assistant Brant Boyer as their special teams coordinator, replacing the fired Bobby April. Boyer, a former NFL linebacker, was the Colts’ assistant special teams coach since 2012. The hiring gives the Jets their fifth special teams coordinator in five years.
