Jones suffered a concussion last Sunday against the Patriots and missed practice all week. It is the second game Jones will sit out this season. He also missed two games in 2011 because of a concussion.
Terrence Cody and DeAngelo Tyson become all the more important today with Jones out.

Cincinnati deactivated tight end Jermaine Gresham, tight end Tyler Eifert, cornerback Terrence Newman, defensive tackle Devon Still, tailback Rex Burkhead, wideout Ryan Whalen and tackle Tanner Hawkinson.
