Andrew Whitworth’s status for Monday’s game against Pittsburgh remains the same as it has the past couple of weeks – close and just waiting to be cleared. What is new is that the veteran left tackle said Wednesday that he had a second procedure done on his knee after suffering a setback during training camp. Whitworth had surgery during the offseason to take out scar tissue in his left knee. “I had a little re-injury and we set the timeline all over got that situation fixed and now we’re close to being back to ready. ... It was a totally different episode that caused another injury because you’re already dealing with something that already has been worked on” Whitworth said. “The quicker you go post-procedure you’re endangering yourself so we had to give ourselves a little time to heal and as soon as we’re ready we’re ready.” During his press conference Monday coach Marvin Lewis sounded optimistic about Whitworth possibly being back for this game. Whitworth though is awaiting the green light from both Lewis and the doctor. After being inactive for last Sunday’s game at Chicago Whitworth’s string of 67 straight games and starts ended. At this point in the week he would still be considered doubtful for the Steelers game but should be closer for Sept. 22 against Green Bay. With the extra day of preparation the Bengals had a light practice Wednesday. Whitworth did not travel with the team to Chicago but was happy to see the performance from Anthony Collins who made his first start at left tackle since 2008 and held Julius Peppers without a sack. Said Whitworth of Collins: “I feel like his agent as much as I’ve promoted him the past 3-4 years and continue to say what a solid player he is. He’s a solid young player who hasn’t had a lot of chances to start on a consistent basis. He had to dedicate himself and some of us helped him along the way but he had to put in the time and he did.” Overall the offensive line allowed Andy Dalton to get hit only twice – a fourth-quarter sack and when Dalton tried a quarterback sneak during the second quarter. “We’ve said all along this is a young line with talent. We’ll get better and Sunday was a testament to the fact it has potential to be a good one” Whitworth added.
