The Arizona Cardinals beat the heat and wilting Green Bay for their first victory of the season.

The Cardinals upset the Packers 20-13 on Sunday at aptly named Sun Devil Stadium, where it was 102 degrees at kickoff and 106 at the beginning of the fourth quarter.

''The heat did take it's toll, and we were able to capitalize on it,'' Cardinals newcomer Emmitt Smith said.

The 106 degrees at nearby Sky Harbor Airport was a record for the date, surpassing the 105 recorded in 1949 and 1984.

''The elements are the elements,'' Packers coach Mike Sherman said. ''People come up to Green Bay, and I don't say we beat them because it's cold out. I say we beat them because we won the game. They beat us because they played better than we did - bottom line.''

Brett Favre, 35-1 when it's 34 degrees or colder, is 12-18 in games when the kickoff temperature is above 70.

Favre, 23-for-33 for 226 yards and a touchdown, drove the Packers (1-2) to the Arizona 7 in the final seconds. But on third-and-goal, his pass was picked off by Dexter Jackson.

''People got their money's worth today,'' said Arizona quarterback Jeff Blake, who completed 20 of 31 passes for 273 yards. ''I heard somebody in the stands say last week that we were robbing them. Well, we're even now.''

Blake threw a 1-yard pass to James Hodgins for the winning touchdown with 3:59 to play.

At Landover, Md., Matt Bryant kicked a 29-yard field goal 4:15 into the extra period for New York.

Seahawks 24, Rams 23

At Seattle, Matt Hasselbeck threw a 3-yard touchdown pass to Koren Robinson with a minute remaining and Josh Brown made the extra point as the Seahawks overcame a 13-point deficit.

At Foxboro, Mass., Tom Brady overcame a sore right elbow and scored on a 1-yard run late in the third quarter to lead the Patriots.

Vikings 23, Lions 13

Dolphins 17, Bills 7

At Miami, Ricky Williams carried a franchise-record 42 times for 153 yards and one score as Miami (2-1) moved into a tie for the division lead with Buffalo and New England.
