Arizona coach Ken Whisenhunt says rookie Ryan Lindley will start at quarterback when the Cardinals play the St. Louis Rams on Sunday.
The coach announced his decision to go with the sixth-round draft pick from San Diego State after practice Wednesday.
John Skelton, benched in favor of Lindley early in last Sunday's 23-19 loss at Atlanta, says he is ''frustrated'' with the situation.
Meanwhile, quarterback Kevin Kolb, out for four games with a rib injury, was able to participate in part of Monday's practice and says he is encouraged by his progress.
Lindley is the third player this year to start at quarterback for the Cardinals, who have lost six straight after starting the season 4-0.
