Arizona coach Ken Whisenhunt will go with rookie Ryan Lindley as the Cardinals' starting quarterback Sunday against St. Louis. Whisenhunt announced Wednesday that the sixth-round pick will replace John Skelton. Lindley took over for Skelton last Sunday in the second quarter of the Cardinals' loss to Atlanta and managed to complete 9 of 20 passes for 64 yards. Skelton was 2 of 7 for 6 yards in the game. Quarterback Kevin Kolb remains slowed by a rib injury that has kept him out since week six. He has been limited him to six games this season. The Cardinals (4-6) are in the midst of a six-game losing streak.
