Although he's been downgraded from questionable to doubtful on the injury list, he's already ruled himself out.
"You could say to be optimistic a week or two, but I'm not able to go this week," Ogunleye said.
Lovie Smith didn't agree with the prognosis.
"Dr. Adewale? Is he a doctor? All I know on the injury is that you're talking about, a muscle strain, is what we're talking about it," Smith said. "Right now that's what our trainers, what they're telling us."
One thing Smith and Ogunleye agree on is that a second opinion on the lower right leg is necessary.
"He's our future," Smith said. "We'll be careful with him and let people tell us exactly what the problem is. Until then we'll keep him out."
The Bears traded for Ogunleye on Aug. 27th and immediately signed him to a six-year $33.4 million deal that included $15.4 million in bonuses.
Because of a contract dispute with the Dolphins he missed all off-season workouts and had no formal training camp. However, he doesn't believe that played into the injury.
"I worked very hard over the off-season to keep my body in shape," Ogunleye said. "I was in great condition and it surprised me a little in the first couple games. But anybody can speculate. If anybody wants to speculate what happened, how it happened, that's for you guys to do that, but I honestly don't think that had that much to do with it."
The six-foot-4, 260-pound Ogunleye totaled 24.5 sacks over the past two seasons, but had just one through five games with the Bears.
This isn't the first time Ogunleye has been sidelined with an injury. At Indiana he was on his way to being a first-round draft pick until he suffered a torn ACL in his left knee six games into his senior season.
The injury led to Ogunleye not being drafted and spending his rookie campaign with the Dolphins on Injured Reserve.
The current injury is nothing compared to what Ogunleye went through to get back on the field.
"Thank God it's not career ending, it's not even season ending so I've got to get out there and rehab it and work it out and put ice on it and hopefully it will heal in time," Ogunleye said.
Meanwhile, Michael Haynes will start in place of Ogunleye.
Haynes, who was a first-round pick in 2003, has yet to start a game in his career. He's played well in spots this season producing one sack.
"You've got to remember, before he was I was planning on starting, so to me I'm just doing the same thing I was doing before," Haynes said.
Despite not registering a sack, Alex Brown arguably had his best game as a Bear last Sunday, as he was consistently in the Washington backfield.
Alain Kashama impressed the coaching staff with his ability to pressure the quarterback in the preseason, but he hasn't been active since the season opener.
"He's more of a thoroughbred, if you will, as far as a guy who can really just run and that's something that I think that he brings to be the table is that good quickness off the ball," said defensive coordinator Ron Rivera.
