GEORGETOWN, Ky. -- Second-year safety Chinedum Ndukwe did not practice Wednesday night and is out indefinitely, Bengals coach Marvin Lewis said.

"He's got a lower leg thing that will hold him out of practice a little while," Lewis said. "When he heals, he'll heal."

Lewis would not elaborate on the injury.

Ndukwe left Wednesday morning's practice on a cart, then returned to practice before having an MRI on his leg.

Ndukwe, a seventh-round pick in 2007 out of Notre Dame, is listed as the team's backup to veteran strong safety Dexter Jackson.

GEORGETOWN, Ky. -- Like clockwork, it seems Corey Lynch is always the first guy on the field for any practice. Unreal.

He's out there tonight. 6:30.

Out: (a running list, and keep in mind many of these are resting); Michael Myers, Johnathan Joseph, Deltha O'Neal, Ethan Kilmer, Angelo Craig, Rudi Johnson, Levi Jones

Still no Ndukwe sighting. He told Chick Ludwig he was getting an MRI on his knee.

Whitworth and Williams doing more snapping with the Qbs.

Still no Ndukwe sighting.

* Looks like Antonio Chatman went down with some sort of injury. but he was treated and he's back up and his helmet is on. Guess it was minor, prbably not even worth leaving up here. But hey, I typed it, so there you go. He just return.

Forgot to mention with all the other stuff today. But IRL drive Jamie Camara was at practice. He's Brazilian, so he had some stuff explained to him. However, he had a more interested audience in kicker Shayne Graham and linebackers coach Jeff FitzGerald.

I'll tell you what, since coming back, I don't think I've seen a ball thrown near Chad Johnson that's been dropped. The guy has looked incredible. Just incredible. That's got to be good for the Bengals this season.

What's not good is the absence of Chinedum Ndukwe.

We've got 1s v. 1s with piped in crowd noise. Looks like some short yaradage situations.

And just as I wrote that thing about Chad, he and Palmer are on different pages and don't hook up. Never fails.

Maybe I should write that the Bengals are going to win the Super Bowl.

Jonathan Fanene just blew up a play. Looked untouched.

Marvin White coming off in the nickel and Simeon Castille.

Carson Palmer. He good. Wow. He just made an unbelievable throw to Glenn Holt rolling to his right.

We have hte second D. Chad Johnson just threw on the breaks and Castille can't catch up and, well, Palmer is unreal. That throw was incredible, right as Johnson came out of his break, on the money.

Nice play by Pat Sims blowing up a play.

 Chad Johnson was just looked at by a trainer, who was focused on his right ankle, he limped back to the ranks. We'll see if he's back. And he is.

Back to 11-on-11, they g deep and Leon Hall was on Johnson step for step.

Goalline work -- Bobbie Willamson the secnd-team line. Carson Palmer, can do quite a bit, I wouldn't run him out there on the naked boot. But that's just me.

Nice coverage by Ahmad Brooks on a pass to Utecht, I think he got hit harder by Jeff FitzGerald than he has by anyone else in camp this year.

More "emergency" work with Williams at center. With Stacy out, Whitowrth is at left tackle, Kooistra at left guard, then Andrews at RG and Anderoson at tackle. With that line, a really nice play to Utecht.

Ryan Fitzpatrick has moxie.

Shotgun snap by Williams looks more like a punt snap. The next one he gets on target.

Willie ate up Geathers. Some talking between the two.

WR Travis Brown has been waived with an injury settlement.

Brown was a rookie free agent signee out of New Mexico. He was originally signed and released by the Seahawks.

The Bengals' official team website is listing Rivers' contract as a five-year deal worth $23 million.

ESPN.com reported it's a six-year deal that voids to five.

From Marvin Lewis:

"We'll get started, with Keith (Rivers) being here, and as we said in the statement, he'll catch up very quickly and assume the opportunity very quickly. We'll see how we go through the week and see whether we play him, or how much. unless I can find something major, I expect him to play some. With that, I guess, we're about done ... "

"Well, I think it's pretty true the guys who graduate from college20when they get into the NFL, they generally are more of the successful players, especially when they're high-picked because they have taken care of business both on the field and off the field. They have a higher success rate with anything they touch in life, and I think Keith will be one of those players."

On the tight ends:

On Jeremi Johnson:

"He’s with the day every day and he’s been outstanding. When I feel good about where he is and we feel like he’s passed his physical we’ll allow Jeremi to come back and practice with pads on or practice whatever the dress of the day is of the football team"

Jeff Fitzgerald:

"He looked like he’s been working out, he looks like he’s in fair shape right now, we cut his reps a little bit, we let him run with the second bunch to get filled in a little bit. He remembers. He’s got a good memory. He took good notes, he did a good job in spring, so he comes back with some knowledge from the install we had this spring."

"He’s ready to play. He was extremely excited to be back in camp and be back with the guys in the room. He walked in there and all the guys were happy to see him last night. The first thing he said, they were all jabbing him and doing this that and the other to him, but he said, ‘you know what? You guys are my family, and I’ve missed being here.’"

"The thing that’s great with Keith, I got to know him a little bit before the draft through workouts and combine, and what you get a feel for the guy is he’s a mature man. You knew coming in he was going to make a quick transition, not just from an athletc standpoint, but with all the things that go with being a first-round pick, being an NFL player and highlight rookie. I think he’s ready, we’ve just got to get him reps and working out here. Expectations are high, I really feel like they’re going to be met in a short period of time."

* Also, Lewis said Ndukwe was OK, called him "Paul Pierce." I heard Leon Hall make the same joke. Ndukwe said he was fine.
