No one seems concerned, but the state of Texas wants to make sure.
Featherweight king Marco Antonio Barrera, in San Antonio to prepare for his Nov. 15 superbout at the Alamodome against Manny Pacquiao, has been asked to undergo a battery of neurological tests before the Texas boxing commission will issue him a license.
In 1997, Barrera underwent brain surgery to repair a small group of malformed blood vessels in his brain, a minor abnormality Barrera had since birth.
During the surgery, a series of tiny, protective implants were inserted. The surgery went off without a hitch and Barrera resumed his boxing career.
