The cornerback's appearance against the Jacksonville Jaguars last week was his first of 2013, having missed the start of the season with a foot sprain.
The 35-year-old told the team's website: "I'm kind of a perfectionist when it comes to my game. It's something I've been looking at and making sure I get a little better every week."
Head coach John Fox added: "I think, overall, pretty good. I thought we definitely cut down on our explosive passes, we cut down the point total, which are critical factors in winning and losing games. Like everybody, I think there's room for improvement."
Bailey made six tackles during the 35-19 win.
