ProFootballTalk.com reported, citing sources close to Skelton, he would miss 2-4 weeks. Kolb will start Sunday at New England and in Week 3, when the Philadelphia Eagles are at Arizona.
Kolb was acquired by the Eagles in July 2011 and signed to a seven-year, $63 million contract before he took a snap in training camp. He hasn't rewarded Arizona's faith in his promise but Kolb, who has made $27 million in just over 14 months with the franchise, delivered in relief to lead the Cardinals past the Seahawks on Sunday.
Skelton earned the starting job over Kolb in a stagnant quarterback competition in training camp.
