"Kevin Kolb is doubtful to return in time for the Arizona Cardinals' Week 11 tilt against the San Francisco 49ers, according to sources with knowledge of the situation.

John Skelton is in line to continue taking reps with the first-team offense, with Kolb still dealing with a series of foot injuries.

In addition to his turf toe, Kolb had some ligament damage in his foot, a bone bruise and a significant sprain. Kolb might not be be able to practice this week at all and has not played since a Week 8 loss to the Baltimore Ravens."
