On Friday, defensive end Carlos Dunlap sprained his knee early in the team's second series in the preseason opener versus the Jets. At Sunday's practice, Bengals head coach Marvin Lewis made the proclamation to the media that Dunlap would be out for the next four weeks. By that timetable, it's possible that Dunlap would be back by the regular season opener against the Ravens, but it's not a definite by any stretch of the imagination.
Not only does there seem to be a confusion on the line of communication here, but there seems to also be a complete lack of it, if one were to believe what Dunlap has said here. Still, it would seem that if Dunlap's "personal timetable" is accurate, then perhaps the extra week that Lewis threw on the timetable might be just be as a precautionary measure to make sure that Dunlap is fully healthy for the big week one matchup against the division rivals.
Then again, ultimately this won't be Dunlap's decision--it's going to be Lewis'.
