Long played right guard for Steelers from 1984 to 1991. In 2005, when he was 45, he killed himself by drinking antifreeze, the Pittsburgh Post Gazette reported. The Brain Injury Research Institute examined his brain and saw evidence of damage that might well have contributed to his suicide. "Terry Long committed suicide due to the chronic traumatic encephalopathy due to his long-term play." Dr. Omalu told the newspaper.
