Researchers have confirmed that a former San Diego Chargers lineman who died of suicide at 25 had the brain disease known as chronic traumatic encephalopathy.
Adrian Robinson Jr.'s diagnosis was confirmed Wednesday through officials at the NFL brain bank at Boston University.
Family lawyer Ben Andreozzi says Robinson had several concussions during two seasons in the league. The family has not filed suit over his May death in Philadelphia.
Robinson, of Harrisburg, played two games as a San Diego Chargers in the 2013 season. He also played for Temple University before playing for Pittsburgh and Denver in 2012 and 2013.
Scientists continue to debate the potential links among concussions, CTE and suicide.
Former Chargers linebacker Junior Seau's suicide, three years after he retired, shocked the football world as well as his hometown. He was diagnosed posthumously with CTE.
Concerns about repeated concussions have led to congressional hearings and new rules on when student and professional athletes can return to play.
