(CNN) - Hall of Fame quarterback Dan Marino has joined the concussion lawsuit against the national football league.
Marino, along with 14 other former players and one spouse are seeking financial compensation for game-related injuries. They accuse the League of misleading players about the dangers of concussions. The lawsuit alleges the NFL knew concussions could lead to symptoms of post-traumatic brain injury. Symptoms include headaches, dizziness, memory loss, dementia and alzheimer's disease.
No specific symptoms are alleged for Marino who retired in 1999 after playing 17 seasons for the Miami Dolphins.
