Just as it was getting good.

Bengals rookie wide receiver Mohamed Sanu, coming off a two-touchdown game extending his touchdown streak to four games against the Oakland Raiders, appeared on Thursday's injury report as limited participation. Which means something happened during Thursday's practice.

According to the local beat writers, Sanu will be examined by the medical staff Friday morning. Though ominous, it could mean that there's some swelling going on and perhaps overnight will show the training staff the severity of Sanu's apparent injury. We're totally speculating at this point.
