PHILADELPHIA (AP) -- Philadelphia Eagles defensive coordinator Jim Johnson has addressed the media for the first time since being diagnosed with a recurrence of cancer. He says he's feeling "good." He has continued to perform his duties while undergoing treatment for skin cancer. He's using a cart to traverse the fields while the Eagles hold their first minicamp of the offseason. Following practice Saturday morning he said he's still going through treatment. He says he's got pain in his back, where a tumor has formed. He's been using a cane to walk. Johnson turns 68 this month. He was first diagnosed with cancer in 2001. Copyright 2009 Associated Press. All rights reserved.
