The Arizona Cardinals blew a 17-point lead to the lowly Detroit Lions and needed to make a pressure-packed play in the closing minutes to avoid an embarrassing defeat.

Kurt Warner threw a 5-yard touchdown pass to Anquan Boldin with 1:54 left, lifting Arizona to a 31-24 win over Detroit Lions on Sunday.

"A win's a win," Warner said. "We are one step closer to our goal."

Arizona (9-5) took the final step later in the day, clinching the NFC West when San Francisco lost at Philadelphia. The Cardinals have won consecutive division titles for the first time since 1974-75.

"We're not happy with how we played," Larry Fitzgerald said. "We know we need to improve, but the opportunity to win double digits, I don't know the last time a Cardinals team was able to do that.

It wasn't in Fitzgerald's lifetime.

The Cardinals haven't won 10 games since 1976.

The Lions (2-12) had the ball with 1:46 left with a chance to come back, but gained just 7 yards, and lost their fourth straight game.

Detroit coach Jim Schwartz wasn't encouraged that his team competed more than it did in a 48-3 loss last week at Baltimore.

"We could've jogged out to the field today and it would've been a better effort," Schwartz said.

Arizona led 17-0 at halftime, then let the Lions make it 17-all in the third quarter and 24-all with 3:48 left.

"You're not going to win a game playing the way we played, especially in the first half," Schwartz said. "We put ourselves in a hole."

The Cardinals went 58 yards on their game-winning drive, gaining 34 yards on Beanie Wells' run, and Boldin broke two tackles on a third-and-3 to score to give Warner two TD passes.

"When we buckled down and we had to make plays, we did," Warner said. "But for whatever reason we didn't sustain that throughout the game. That's what allowed them to get back into it."

Warner was 23 of 37 for 233 yards with two TDs and an interception.

Wells ran for a career-high 110 yards and had an 18-yard, tackle-breaking TD that put Arizona ahead 24-17 early in the fourth quarter.

Fitzgerald's TD catch gave Arizona a 7-0 lead late in the first quarter and finished with four receptions for 36 yards, less than a week after injuring his right knee in a loss to the 49ers.

Arizona's Dominique Rodgers-Cromartie had two interceptions.

Daunte Culpepper, starting for banged-up Matthew Stafford for a second straight week, completed half of his 12 passes for 64 yards with an interception and was benched in the second half.

"Daunte didn't drop punts, Daunte didn't drop passes, Daunte didn't jump offside," Schwartz said. "A quarterback is judged by points and we weren't getting that done."
