Rickert told The Philadelphia Inquirer on Friday that it is "definitely a possibility" that Patterson will return, but acknowledged that surgery hasn't been ruled out as an option. The 27-year-old defender has been diagnosed with a brain condition that the Eagles have described as a brain AVM, which are malformations or tangles of arteries and veins that alter blood flow.
Rickert said an announcement is expected Monday regarding Patterson, who visited neurologists last weekend and received positive medical reports.
It had been thought that the 6-foot-1, 300-pound Patterson would be cleared to participate in football-related activity Friday. He returned to training camp at Lehigh University last Friday, but has yet to participate in drills.
