Though he was listed as a full participate during Monday's walkthrough, Bengals cornerback Dre Kirkpatrick didn't practice on Tuesday and Wednesday, dealing with the remnants of a concussion that he suffered two weeks ago.
It's still an issue.
Per the team's injury report, Kirkpatrick won't play this weekend, which we can presume suggests that he still hasn't passed concussion tests to resume onfield activity.
With Kirkpatrick out, figure that Jason Allen will get a chance to play his third game of the season.
