It's doubtful the Cardinals are going to announce a starter at quarterback until shortly before Sunday's game against the Vikings.
Kurt Warner and Matt Leinart split snaps again in practice Friday, with Leinart receiving more work in certain situations than usual. Warner, recovering from a concussion, has reported improvement this week. He and Ken Whisenhunt are hopeful that Warner will play, but they aren't assuring it. Warner decided last Sunday morning that he couldn't go against the Titans.
Knowing that could happen again, Whisenhunt divided snaps between Warner and Leinart this week.
