BETHLEHEM, Pa. (AP) — Eagles trainer Rick Burkholder says defensive tackle Mike Patterson has a brain condition, and may require surgery.

Burkholder says Thursday morning that Patterson is undergoing further tests.

The 28-year-old Patterson was hospitalized after suffering a seizure Wednesday morning at training camp at Lehigh University. The 6-foot-1, 300 pound Patterson has been diagnosed with arteriovenous malformation (AVM), which is the tangling of blood vessels near the skull.

On Wednesday, Patterson dropped to the ground between plays during a morning practice, and the player began violently shaking. He was immediately tended to by Burkholder and his staff, with assistance from rookie Danny Watkins, a trained firefighter, and taken by ambulance to a hospital.
