TEMPE, Ariz. -- Arizona Cardinals coach Ken Whisenhunt said he doesn't expect to decide who will start at quarterback Sunday night against the Minnesota Vikings until just before game time.
Kurt Warner and Matt Leinart split practice time with the starters again Thursday, and Whisenhunt said he hasn't decided who will be the No. 1 quarterback this weekend.
"You want to make the decision now, but certainly we've got to see how everything goes with Kurt," Whisenhunt said. "Even though he may feel great today, there might be a situation where something could come up."
Warner, who sustained a concussion during a Nov. 22 game against the St. Louis Rams, took all the practice time with the starters last week but sat out Sunday's 20-17 loss at Tennessee because of lingering symptoms. That left Leinart the starter without much preparation.
Warner said he feels much better this week, but Whisenhunt is putting off his decision on a starter in case there are any late setbacks.
"You've just got to make sure," Whisenhunt said. "He could be ready to go Saturday and then something could happen Sunday, and certainly, once again, you would err on the side of caution. I'm sure in some manner or shape it will be a Sunday decision."
Meanwhile, the Cardinals could be without starting left tackle Mike Gandy, who hasn't practiced this week because of a pelvis injury. Jeremy Bridges would be Gandy's replacement. If Gandy can't start, it would end a string of 31 consecutive games in which Arizona has started the same offensive line.
Tight end Stephen Spach also didn't practice Thursday because of a sore knee. Three starters -- linebacker Karlos Dansby (shoulder), cornerback Bryant McFadden (knee) and running back Tim Hightower (thumb) -- were limited.
