In addition to his turf toe, Kolb had some ligament damage in his foot, a bone bruise and a significant sprain. Kolb, who hasn't played since a Week 8 loss to the Baltimore Ravens, might not be able to practice at all this week.
"I am just anxious to get back on the field and prove what I can do," Kolb said.
When Kolb does return, team sources expect the coaching staff to go back to him as the starter. The team made a significant investment in Kolb in terms of money and draft picks and view him as a potential franchise quarterback despite his struggles this season. The Cardinals signed Kolb to a six-year, $65 million contract after acquiring him in an offseason trade that sent Pro Bowl cornerback Dominique Rodgers-Cromartie and a second-round pick back to the Philadelphia Eagles.
