Knoxville, Tenn. (WVLT) -- Pro football Hall of Hamers Tony Dorsett, Joe Delamiellure and Leonard Marshall have all been diagnosed as having signs of CTE or brain trauma...
Dorsett of couse was an All Pro for many years with the Dallas Cowboys.
Before that, he played his college football at the University of Pittsburgh under then panthers head coach Johnny Majors.
The Vol legend is concerned about his former pupil and good friend who played a physically demanding position.
Autopsies of more than 50-ex NFL players have shown sings of CTE. This is the first time doctors have found signs of the crippling disease in living former players. CTE is a disease with no known cure.
