Cornerback Kelly Jennings practiced for the first time as a member of the Bengals Friday morning after they got him from Seattle in a trade but was listed as doubtful after going limited. In the last stages of a hamstring problem when he arrived 10 days ago, Jennings had looked good on the side for a week before putting on the helmet Friday.
Safety Taylor Mays (knee) was dressed but didn't have a helmet and worked on the side and was also listed as doubtful. Running back Brian Leonard (finger) was limited Thursday but went full go and is probable. The only starter the Browns listed as doubtful is right tackle Tony Pashos (ankle).
Bengals head coach Marvin Lewis held a rare Friday morning practice on the grass fields. Usually the Bengals work on the grass Wednesday and Thursday and work in Paul Brown Stadium Friday for their last practice of the week. But this week it's been reversed, primarily because of the rain and the fact they're playing Sunday's opener in Cleveland (1 p.m.-Cincinnati's Local 12) on grass.
There's a 30 percent chance of showers and thunderstorms Sunday in Cleveland, according to the National Weather Service in Wilmington, Ohio, with a kickoff temperature of about 70 degrees and reaching the mid-70s by the end of the game under mostly cloudy skies. A light wind out of the west is projected at five to 10 miles per hour.
