Arizona Cardinals quarterback Kevin Kolb is expected to be miss several weeks with rib and chest injuries.
The Cardinals have ruled Kolb out of Sunday's game against Minnesota, ESPN.com reported Tuesday.
Kolb's injuries include detached ribs from his sternum and a sprained sternoclavicular that he sustained in last Sunday's game against Buffalo on a broken play. He has taken a beating in the past three weeks with 23 sacks.
John Skelton came in last week to replace Kolb and likely will be the starter Sunday. He started the season opener for the Cardinals (4-2).
