Kevin Kolb day-to-day with bruised ribs

X-rays on Cardinals QB Kevin Kolb's ribs came back negative.  He's considered day-to-day with a contusion.  "He has a bruise in his chest and that makes it kind of tough to rotate, move," HC Ken Whisenhunt said. "I think he'll probably be practicing sometime this week."  Kolb needs to get back on the field in a hurry after last night's abysmal showing.  QB John Skelton was clearly more effective, completing 4 of 6 passes for 32 yards and leading the offense on a 90-yard scoring drive.  We'd consider this QB battle a dead-heat right now.  Avoid the situation in fantasy drafts.
