Former Oakland Raiders linebacker Neiron Ball is in a medically induced coma after a brain aneurysm ruptured Sept. 16, the team said Tuesday.
Ball, 26, was diagnosed while at Florida with with a rare, congenital condition called an arteriovenous malformation (AVM), in which the brain's blood vessels get tangled and rupture. He underwent emergency surgery after physicians discovered a brain bleed prior to his sophomore year, and he sat out the 2011 season.
