AMES, Ia. — Iowa State's quarterback conundrum may have an answer this week.

Cyclones coach Matt Campbell said that quarterback Kyle Kempt is "doubtful" for Saturday's game against No. 6 West Virginia.

Campbell had said he was waiting to name a starter between Kempt and true freshman Brock Purdy. Kempt was the starter when the season started. Purdy came off the bench last week and guided Iowa State to a 48-42 win over No. 21 Oklahoma State.

With Kempt unlikely to go Saturday, Purdy will take over the starting spot.

Here's what else we learned

David Montgomery is "day-to-day." The running back missed last Saturday's game with a shoulder injury. Campbell said he would have more of an idea by Wednesday of Montgomery's status.

Black uniforms could be coming for Saturday. Iowa State fans may finally get their wish with black uniforms for Saturday's game. Emphasis on may. Campbell wouldn't say one way or another if the new ones would be coming out.

"The wrong guy you're asking," Campbell joked.

Purdy needs to keep getting better. The true freshman was phenomenal in his most extended action this season, passing for 318 yards and four touchdowns and running for 84 yards and one more score. But as good as Purdy was, he wasn't perfect.

"There's a lot he can clean up and continue to work on," Campbell said. "We'll have to continue to do that if we want to continue to get better."

Campbell's first recruiting talk sold him on Purdy. Iowa State first started taking a look at the Arizona native back in January after Campbell saw film from Iowa State assistant scouting director Taylor Mouser. Campbell then called Purdy's high school coach. But what really sold Campbell was the 90-minute conversation they had on the phone that night.

"Having really meaningful conversations at 17 years old is hard to find today," Campbell said.

Braxton Lewis is earning a scholarship. And for good reason. The walk-on has been one of the biggest bright spots for the Iowa State defense. He's grabbed an interception in three straight games and is tied for fourth nationally in interceptions per game. On Monday, he was named the Big 12 Conference's Big 12 defensive player of the week.

"As soon as we get an opportunity to reward him, he deserves it," Campbell said.

Slowing down West Virginia quarterback Will Grier won't be easy. It may be impossible, Campbell said. Grier leads the Big 12 in numerous categories, including passing yards per game (363.8). But stopping Grier isn't the goal. Slowing him down is.

"To sit there and say you're going to stop him is a naive comment," Campbell said.
