Ball State cornerback Antonio Phillips did not work out at the school’s pro day today.

Phillips’ agent, Ross Jones, told Mike Garafolo of NFL Media that Phillips underwent a microdiscectomy on March 17. A microdiscectomy is a minimally invasive surgery to provide relief from pain caused by a lumbar herniated disc.

Doctors gave Phillips a six-week recovery timeline, per Garafolo.

Phillips measured (5 foot 11), weighed (193 pounds) and did a flexibility test Friday.

He remains a mid- to late-round prospect.

In four seasons, Phillips played 35 games, made 137 tackles and totaled eight interceptions and 18 pass breakups.
