In the wake of Junior Seau's death, Ravens wide receiver Anquan Boldin is trying to be proactive about potential brain damage. "I'm doing research myself to try to find ways to rectify brain damage," Boldin said. Boldin said he had been consulting with a doctor who has advised him how the use of a hyperbaric chamber -- which produces greater air pressure -- could protect against long-term problems to a brain whose owner has been subjected to multiple concussions.
