FOR IMMEDIATE RELEASE; WED., NOV. 28, 2012
FROM CINCINNATI BENGALS PUBLIC RELATIONS 

BENGALS ROSTER MOVE
The Bengals today returned C Kyle Cook to practice, on a roster exemption.
Cook is on the Reserve/Injured list, due to an ankle injury suffered in preseason, but he was designated for possible return under new NFL rules for 2012. 
Today starts a three-week window during which Cook may practice with the team without being counted against the 53-player active roster limit. He could be added to the roster at any time during this three-week period.
Cook (6-3, 315; Michigan State) is a fifth-year NFL player. He finished last season with a streak of 50 consecutive Bengals starts, tied for longest on the team at the time.
