The Bengals have lost 26-year old WR Andre Caldwell for the rest of the season as he has been placed on the Injured Reserve List due to a groin injury.  Caldwell played in 13 games for the Bengals this year and he caught 37 passes for 317 yards (8.6 avg) with 3 TD grabs.  He has played in 51 games in his four years with the Bengals and he has caught 124 passes for 1,172 yards (9.5 avg) with 6 TD grabs.  This is going to hurt the Bengals a little bit as Caldwell was their #3 WR this year.

The Bengals will be without 35-year old starting right guard Bobbie Williams for the rest of the year due to a broken ankle.  Williams played in 9 games (all starts) for the Bengals last year.  He has now played in 118 games (all starts) in his first 8 years for the Bengals.  This is going to hurt the Bengals as Williams has plenty left in his gas tank.

The Bengals have placed 26-year old DT Pat Sims on the Injured Reserve List, ending his season due to a severe ankle injury.  Sims played in 11 games for the Bengals this year and he had 20 tackles, 1 sack and 1 tackle for a loss.  He has now played in 52 games in his first four years with the Bengals and he has 121 tackles, 5 sacks, 6 tackles for a loss, 1 fumble recovery and 1 pass defensed.  The Bengals will likely miss Sims some as he has been a solid backup tackle.

The Bengals will be without 26-year old CB Leon Hall for the rest of the year.  They have placed him on I.R. due to a ruptured left Achilles tendon.  Hall played in 9 games for the Bengals last year and he had 32 tackles, 7 passes defensed, 2 interceptions and 1 fumble recovery.  He has now played in 73 games in his first five years with the Bengals and he has 290 tackles, 78 passes defensed, 20 interceptions (1 returned for a TD), 5 forced fumbles, 2 fumble recoveries and 6 tackles for a loss.  This is a HUGE loss for the Bengals as Hall is one of the best corners in the NFL.

The Bengals have lost 25-year old WR Jordan Shipley for the rest of the season due to a torn left ACL.  Shipley played in both games for the Bengals this year and he caught 2 passes for 14 yards (7.0 avg).  He has now played in 15 games in his first two years for the Bengals and he has caught 52 passes for 600 yards (11.5 avg) with 3 TD grabs.  The Bengals will need 26-year old Andre Caldwell to step up and be the #3 WR the rest of this year.  Caldwell has played in 2 games for the Bengals so far this year and he has caught 3 passes for 27 yards (9.0 avg) with 1 TD grab.  Andre Caldwell has now played in 40 games in his first four years with the Bengals and he has caught 90 passes for 882 yards (9.8 avg) with 4 TD grabs.

The Bengals will be without 25-year old LB Keith Rivers for the next six weeks after wrist surgery.  Rivers played in 15 games for the Bengals last year and he had 77 tackles, 5 tackles for a loss, 1 sack and 2 passes defensed.  He has now played in 35 games in his first three years with the Bengals and he has 186 tackles, 9 tackles for a loss, 2 sacks, 1 forced fumble, 5 passes defensed and 2 interceptions.  This is going to hurt the Bengals as Rivers is a pretty solid linebacker.

The Bengals have placed 27-year old CB Adam “Pacman” Jones on the PUP list due to neck surgery and he will miss at least the first six games of the 2011 season.  Jones played in 5 games for the Bengals last year and he had 14 tackles, 3 passes defensed, 1 interception, 1 forced fumble and 2 fumble recoveries (one returned for a TD).  He also returned 5 punts for 33 yards (6.6 avg) and 7 kickoffs for 134 yards (19.1 avg) last year for the Bengals.  The Bengals are going to miss Jones, as he got his career back on the right path on the field last year.

The Bengals have lost 23-year old rookie linebacker Dontay Moch for the next 8 weeks after he broke his left foot in the pre-season opener against the Lions.  He made 1 tackle against the Lions.  Moch was picked in the 3rd round because the Bengals had high hopes for him down the road.  He was going to provide depth this year while learning on the job.  This is a bigger setback for the Bengals than most probably believe because Moch was going to, and he still might, get a lot of P.T. in 2011.

The Bengals have lost 24-year old rookie linebacker Roddrick Muckelroy for the season.  He ruptured his Achilles tendon at practice last Saturday.  Muckelroy played in 14 games as a rookie last year for the Bengals and he had 10 tackles and 4 forced fumbles.  The Bengals are going to miss him on special teams and Muckelroy was going to get a shot in training camp to earn more reps at LB in 2011.

UPDATE:  (9/4/2011) – The Bengals have placed Roddrick Muckelroy on the Injured Reserve List.

The Bengals have placed 26-year old RB Brian Leonard on Injured Reserve with a ankle injury.  Leonard played in 11 games for the Bengals this season and he carried the ball 9 times for 61 yards  (6.8 ypc).  He also caught 20 passes for 137 yards (6.9 avg) with 1 TD grab this year.  Leonard has now played in 25 games in his first two years with the Bengals and he has carried the ball 36 times for 145 yards (4.0 ypc).  Leonard also has caught 50 passes for 354 yards (7.1 avg) with 1 TD grab in his time with the Bengals.  The Bengals have claimed 23-year old CB David Pender off waivers from the Colts to replace Leonard on the roster.  Pender played in 3 games for the Colts and he had 2 tackles.  He was a undrafted rookie.
