Warren has practiced on a limited basis this week and is listed as questionable with a pectoral injury. He admitted before Thursday's practice that he probably won't play.
Warren wants to make sure that he's fully healthy when he returns. He admits that he rushed back in playing against Dallas the week after suffering the injury.
"I should have been on the sideline in my blues against Dallas and not out there suited up and ready to go to work," Warren said. "Wanting to be on the field with my teammates and playing, it was a bad decision on my part."
Warren has understandably been frustrated about missing time.
"It's been frustrating, but if we were 0-4 it would be really frustrating," Warren said. "Through the first quarter of the season, we're not where we want to be, but we've made a lot of improvements from week to week."
NO HELP: Offensive lineman Bob Lacy says he can't be of much assistance in helping the Browns prepare for the Steelers. Lacy, a sixth-round draft pick of the Steelers this season, opened the season on the practice squad. The Browns signed him to their active roster last week.
"There's only so much (advice) an offensive lineman can give," Lacy said. "You can say how the players play, but you can see that on film."
INJURY WATCH: Steelers running back Duce Staley has been downgraded to questionable with a toe injury.
"I'm so unconcerned about who the starter is," said coach Butch Davis, who noted that it will be a running back-by-committee approach. "Who's in on the first play of the game makes no difference. It's about playing well in all three phases that a running back has to play."
Green seemed upset when approached by reporters this week. He's refused comment about not playing in the second half against the Washington Redskins.
"It goes without saying (why he's upset)," Suggs said.
Suggs is clearly anxious to get his first career start. He said he felt sore last Monday, but the soreness wasn't related to the neck injury he suffered in preseason.
"It was normal playing-football sore," Suggs said. "I thought that playing after four or five weeks off that I was going to be sore. I just have to get through it."
