Philadelphia Eagles defensive tackle Mike Patterson will not participate in the team's training camp as he recovers from offseason brain surgery.
Patterson underwent a procedure in January to repair an arteriovenous malformation in his brain that caused him to suffer a seizure in training camp prior to last season.
The 28-year-old was expected to be healed in time for the start of camp, but a recent X-ray and CT scan was reviewed by Dr. Robert Spetzler, who performed the surgery, and he decided Patterson would need some more time to fully heal.
"I think what the physician wanted to see was how the healing was with the cranium where they took the piece of the skull away to do the procedure," said Eagles head athletic trainer Rick Burkholder. "He wasn't totally happy with it."
Patterson will be placed on the reserve/non-football injury list and will remain at training camp.
The Eagles selected Patterson with the 31st overall selection in the 2005 draft and he has appeared in 110 games for the team, collecting 332 tackles, 15 1/2 sacks and an interception.
