On Wednesday, Mike Singletary briefly addressed the unexpected departure of assistant Johnnie Lynn, 53, who resigned this week after five years on the staff for what the team termed "personal reasons." Singletary began by saying of Lynn's departure, "I lose a good friend." Later, he said, "Johnnie and I remain friends." Singletary was asked if the resignation was mutual. "When personal matters come up, it's very important that you really don't get into, 'Was it this, was it that?'" Singletary said. "I just want to say that a personal issue came up and Johnnie is going to have to handle it in the best way possible. I wish him all the luck in the world."
