John Skelton will start at quarterback for Arizona Sunday after rookie Ryan Lindley proved ineffective the past two games, Coach Ken Whisenhunt said Wednesday. Skelton, who had been starting in place of the injured Kevin Kolb, was benched in favor of Lindley in the first quarter of the Cardinals\' Week 11 game against Atlanta when he completed 2-of-7 passes for 6 yards. Lindley played the rest of that game and started the next two, but failed to throw for any touchdowns and had five passes intercepted. Skelton has thrown for 1,058 yards with two touchdowns and five interceptions in six games (five starts) this season. Kolb, who led the Cardinals to a 4-0 record before being hurt in Week 6, is out for at least another week with a rib injury. Arizona has lost eight in a row.
