Boldin trying to reduce risk of brain trauma

Ravens wide receiver Anquan Boldin doesn't shy away from contact. His helmet-to-helmet collision from four years ago proves that.

That doesn't mean Boldin lacks concern over the long-term effects of concussions on the brain. He told CNN's World Sport (you can see the video on the Ravens' official website) that he has been talking to a doctor in Florida who is studying how hyperbaric oxygen therapy has led to the brain repairing itself.

"I'm doing research myself to try to find ways to rectify having brain damage," said Boldin, whose only concussion came from that knockout blow by Eric Smith.

Perhaps Boldin could sit down with former teammate Ricky Williams, who recently said he doesn't believe in the link between concussions and long-term brain trauma. At the very least, they could exchange ideas on "alternative therapy."

Before talking about hyperbaric therapy, Boldin discussed the impact of Junior Seau's suicide. While it's unknown whether brain trauma was a factor in Seau's death, the tragic incident has ignited talk about head injuries in football.

"It makes you think what effect does this game have on you long term," Boldin said. "I think every NFL player has that question in the back of his mind."
