Broncos' quarterback Jay Cutler doesn't have the hairline fracture in his left leg he feared. An MRI exam Monday was negative, but coach Mike Shanahan said he didn't know if Cutler would practice much this week or be under center Sunday at Kansas City. "He doesn't have a stress fracture, which is a positive," Shanahan said. "The X-rays were negative; the MRI was negative. So, we'll see how sore he is. Right now he's quite sore. And we'll get a chance to see how he feels on Wednesday." Cutler took a helmet to his lower leg, which was badly bruised, in the first half of the Broncos' 44-7 loss at Detroit on Sunday. He was carted off the field, and although immediate X-rays were negative, Cutler said he feared his leg was broken.
