There could be more changes in the secondary this week.

Terrence Frederick, a seventh-round pick in the 2012 draft, says that he’s been mixing in with the first-team defense during practices this week. He does not know yet if he will start Monday night against the Chicago Bears, but is preparing as if he will.

“I’ve just been preparing myself if I’m going to be up this week,” Frederick said. “Obviously I’ve been working in and out with the starting defense. We’ll just see what Monday brings.”
