J.R. Rickert, the agent for Philadelphia Eagles defensive tackle Mike Patterson said it’s too early to say that a brain condition called arteriovenous malformation triggered the seizure his client suffered Wednesday.

“Rick [Eagles trainer] Rick [Burkholder] spoke to one doctor who evaluated Mike that’s leaning toward the diagnosis of AVM,” Rickert told the Associated Press. “Two other doctors are not leaning toward AVM. They haven’t ruled it out, but they’re not leaning in that direction at all. They’re saying it’s premature to diagnose him in that capacity.

“We’re going to take Mike to a fourth specialist to get an opinion. After we get that opinion, Mike and [his wife] Bianca will get together and make a decision about the best course of action based on which opinion they want to follow.”

Mike Patterson, the Philadelphia Eagles defensive tackle who suffered a seizure in practice Wednesday, is suffering from an arteriovenous malformation, a brain condition in which blood vessels near the skull are tangled.

Eagles trainer Rick Burkholder told ESPN that Patterson, who was unconscious for four minutes during the episode, will require surgery (possibly vascular) or radiation therapy to correct the condition, which is generally congenital. Patterson could be released from the hospital today.

Burkholder said that an MRI showed no bleeding in the brain, which can be a complication of an AVM. Seizures, headaches or noises in the other ear are other symptoms, according to the Mayo Clinic website.

Patterson, 27, is entering his seventh season with the team. He was its 31st overall pick out of USC in the 2005 draft.
