"We couldn't take the risk of him playing from that point," Whisenhunt said.
Hall appeared to be rattled by Chris Clemons' blindside sack early in the third quarter. Clemons hit Hall in the back and Hall fumbled at the Arizona 11. He was watched closely on the sideline by trainers and was replaced by Derek Anderson on Arizona's next possession.
"I'll be all right," Hall said.
"I was a little woozy," he added later. "I got a little nauseous or whatever but I'll be OK."
In a week of heightened awareness on illegal hits to the head, Clemons' sack appeared to be a clean shot to Hall's back. There was no penalty on the play.
Hall was struggling before leaving the game. Making the first road start of his career, Hall was 4 of 16 for 35 yards with an interception and finished with a passer rating of 13.5.
Anderson led Arizona on a touchdown drive after entering, but Whisenhunt said he would be moving forward with Hall as the Cardinals quarterback as long as he's healthy.
"This is a tough environment to play in. Give him credit, we knew with a rookie quarterback that's part of the progression, that's part of what you have to live with," Whisenhunt said. "I don't have any doubt that Max will bounce back from this and play well. Like I said we will look and what we are doing we'll tailor it a little more maybe cut somethings down and I think we'll be just fine."
