Former Oakland Raiders linebacker Neiron Ball was placed in a medically induced coma after suffering a brain aneurysm on Sept. 16.

Ball — who was a fifth-round choice by the Raiders in the 2015 draft out of Florida — missed the entire 2011 season at Florida after suffering from an arteriovascular malformation condition, which is where the brain's blood vessels get tangled and rupture. This is a rare condition that affects less than one percent of the population. He returned to play in 2012, made his first career college sack against Jameis Winston and Florida State in 2013, but had his senior season in 2014 cut short after suffering a knee injury.

Despite serious health concerns, Ball — who was projected to go undrafted in 2015 — was picked by the Raiders with the No. 161 overall selection. In his rookie season, Ball played in six games, making two starts, recording four tackles, a sack and a fumble recovery for the Raiders. Ball was cut by the Raiders at the end of training camp in 2016.
