Trestman said the Bears are "hopeful" but need "to be reserved about it as well." Going up against Ndamukong Suh and the Lions would be difficult enough for a healthy quarterback, let alone one who might be limited. And the last thing the team needs is a setback for Cutler, even if McCown has been playing well.
"There is no gray area in this decision," Trestman said. "The doctors are either going to say he can play, and that means he can play without any sense that there's going to be (a setback). ... If he is then he'll go. That's really it."
"The way he rallies the guys in practice,Carolina Panthers Jersey Cheap, the way he prepares,Cheap Hockey Jerseys, it's contagious, a trickle-down effect," Marshall said. "He affects our coaching staff, he affects players on offense and defense, he's just that type of guy."

NOTES: Trestman said LS Patrick Mannelly has a calf injury and that "it doesn't look good for this week." The Bears signed LS Jeremy Cain,Cheap Basketball Jerseys China, who spent the past four years with Jacksonville and played for Chicago in 2004 and 2005.
His numbers weren't eye-popping — 22 for 41 with 272 yards — but he threw two touchdowns without an interception. He also led an 80-yard drive that lasted just under 9 minutes and ended with a late field goal, helping the Bears prevail 27-20 in their first win at Lambeau Field since 2007.
Cutler said last week that he hopes to be back sooner,Cheap Jerseys From China, and Brandon Marshall said the "worst-case scenario" would have him returning against Detroit.
Cutler told Chicago's WMVP-AM 1000 on Tuesday that he wasn't sure if he would be ready for the Lions. But Marshall sounded confident that he will be ready to play.
"Now, when it comes to Jay,Football jerseys china, he's our leader, he's our captain," Marshall said. "How far Jay takes us, that's how far we're going to go."
Cutler tore his left groin muscle against Washington on Oct. 20 and sat out against the Packers, after the Bears had a bye the previous week. Veteran Josh McCown has played well in his place, but Trestman insisted that won't impact the decision.
Even so, the Bears need Cutler. They need his rifle arm and his play-making ability,Cheap Shoes China, and Marshall was quick to point that out.
The Bears initially said that Cutler would likely be out at least a month and be evaluated on a week-to-week basis after that. But an early return is looking more and more like a possibility.
The Bears (5-3) are coming off a win at Green Bay on Monday night that vaulted them into a tie for the NFC North lead with the Packers and Lions. Detroit visits Sunday, and Cutler's status is up in the air.
"I don't know where he's at really," Trestman said. "He's been running around, working out with the trainers. He spent a lot of time on the off day with (director of rehab) Bobby (Slater), working with bands, redirecting and things like that. It'll be day to day and we'll see more tomorrow. We're hopeful but we've got to be reserved about it as well."
LAKE FOREST, Ill. (AP) — Chicago Bears quarterback Jay Cutler's status for this week's game against Detroit will likely come into clearer focus on Thursday as he recuperates from a groin injury.
He again said Cutler will play when he's ready — and the doctors will determine when he's ready.
"Jay's on the right track," he said. "I think he's going to try it this week. If he can go, he'll go, if he can't, I think he's going to make a very hard decision to rest it a little bit more. But he's definitely put himself in position to make it out there for Sunday."
After Cutler went down against Washington, McCown completed 14 of 20 passes for 204 yards, and he came through with a solid performance against Green Bay.
Coach Marc Trestman said Cutler would have been listed as limited had Chicago practiced on Wednesday. Instead, the team went through a walkthrough.
