Spenser Rositano retires at 20: Sixth concussion cuts Boston College safety?s career short - The Washington Post BC player Spenser Rositano had 2 known concussions in high school and 4 in college. After the 5th he started considering quitting the game. After difficulty recovering from the 6 he did stop. I get the impression: Symptoms and recovery were getting worse each time. His family was nicely supportive; whatever they did to influence him, there seems to also have been a strong dose of "It's your decision, and we're with you whatever you decide."
