Friday notes:Peko, Green probable; Dunlap out; Chilly rain predicted for Sunday

Updated: 2 p.m.

While Bengals nose tackle Domata Peko, who missed the first two practices of the week with a foot problem, looked ready to go after Friday morning's practice on the grass fields next to Paul Brown Stadium, left end Carlos Dunlap was ruled out of Sunday's game by head coach Marvin Lewis.

Peko doesn't miss games and he was listed as probable even though he went limited. The only five he's missed came at the end of the 2009 season when he underwent a knee scope but returned for the playoffs.

But Dunlap (hamstring) missed his third straight day as he worked out on the side. It's looking more and more like he reaggravated the hamstring that knocked him out of the Nov. 13 game against the Steelers when he played in Baltimore last week. Tight end Donald Lee (foot) looks like he's going to miss his third straight game. Like Dunlap, he was listed as doubtful.

Wide receiver A.J. Green (knee) had a full practice for the second straight day Friday and was probable.

Lewiis dismissed quarterback Andy Dalton's injury to his throwing shoulder that limited him Wednesday as more bureaucratic than anything and he's gone full the past two days.

"He's fine," Lewis said after Friday's practice. "The way things go nowadays you have to dot your Is and cross your Ts ... you can't believe there are actually clubs doing certain things that we seem to get memos about."

The rest of the Bengals were probable, although right end Michael Johnson (shoulder) went from going full Thursday to limited Friday. Cornerback Adam Jones (groin) and outside linebacker Vincent Rey (surfacing Friday with a hamstring issue) were also limited and outside linebacker Dontay Moch didn't work because of a migraine.

The Browns are full go in the backfield even though Peyton Hillis (hamstring) was ruled out earlier in the week. He worked Friday, as did Montario Hardesty, and it looks like they're going to get some work.

The National Weather Service in Wilmington, Ohio calls for cloudy skies Sunday and likely showers with temperatures in the low 40s and winds out of the west at about 10 miles per hour.
