"I'm clear with our coaches all the time: We've got to stay back," Lewis said on Monday. "I know everything's been written about what happened with coach Munchak and Reggie and Joey but again, all of that out of the way, let's win a football game and let's do it the way we're coached to do it."
Whitworth said Porter was known for trash talking when he was a player.

"I've got a ton of respect for those guys," left tackle Andrew Whitworth said of the Steelers. "Joey Porter is not one of them. He's not one of the guys I respect very much. He's a guy that has always run his mouth. He's always been disrespectful to people."
"There's no excuse," safety George Iloka said. "We've got to keep our composure as a team. But they (the Steelers) did a good job of dangling that meat in front of us."
Porter was in the middle of a group of players when Jones went after him, bumping an official and drawing the flag.

The two penalties moved the ball from the Cincinnati 47-yard line to the 17, setting up the winning kick.
The conduct of Steelers assistant coaches — offensive line coach Mike Munchak was penalized for grabbing the hair of safety Reggie Nelson in the first half — still bothers the Bengals. The NFL said it's reviewing the conduct of other players and coaches during the game for possible discipline.

"Coaches are supposed to be held to a higher standard when it comes to stuff like that," Jones said. "Even with Mike Munchak grabbing Reggie's hair. Thank God that wasn't me. I wouldn't have just walked away."
