Cincinnati Bengals roster moves, December 8

The Bengals today made the following roster moves:
* Activated C Kyle Cook to the roster from the Reserve/Injured list. Cook (6-3, 315; Michigan State) is a fifth-year NFL player. He suffered an ankle injury in preseason, on Aug. 23 vs. Green Bay, and was placed Sept. 4 on Reserve/Injured, designated as the team’s player eligible for possible return. Cook has been practicing with the team since last week on a roster exemption. Cook opened 2012 preseason as the team’s No. 1 center. He made 50 consecutive Bengals starts through the end of last season, tied at the time for longest active streak on the team.
* Waived WR Armon Binns, a first-year player from the University of Cincinnati. Binns played in eight games this season with five starts, but has been inactive for the last two games and three of the last four. He had 18 catches for 210 yards and one TD.
