Warner has been battling Matt Leinart for the starting job.
"We all want to know," Warner said after practice Wednesday. "For Matt and myself, it'd be nice knowing what the situation would be and be able to move forward with it. The way I look at it more than anything, the sooner it can happen, the sooner we can get past the (interviews and media coverage) that goes with it and you can prepare for the game.
"We know it's getting close and you get that anxiety and excitement knowing the decision has to be made soon. I am sure coach understands that and he'll make the decision as soon as it's necessary."
Arizona (2-1) is coming off a 24-0 win at Oakland last Saturday night despite Leinart throwing three interceptions in less than two quarters.
Whisenhunt said Warner is starting against the Broncos (1-2) because of the difference in playing time in the preseason.
So far, Leinart has taken 57 snaps with starts against New Orleans and Oakland. Warner sat out the preseason opener against New Orleans and started against Kansas City and has taken 30 snaps.
"Hopefully we'll get in enough snaps with the first (offensive) line that both can play," Whisenhunt said. "I just wanted to make sure Kurt gets his timing with the ones for this game, much like we did in Kansas City."
