Somewhere, Joe Namath had to be smiling.

While Brett Favre isn't exactly a reincarnation of Broadway Joe, he sure looked like Broadway Brett on Sunday. The longtime star quarterback did something for the Jets he never accomplished during his storied stint in Green Bay, throwing for six touchdowns in a 56-35 victory over the Arizona Cardinals.

"Throwing six touchdown passes was awesome," said Favre, who was plagued by a sore ankle during the week. "That had nothing to do with how I felt I played. It was one of those games. More importantly, I felt the overall game itself, I managed it well.

"It's just one game. Don't expect six touchdowns every week, but we, as an offensive unit, should see and expect a lot of ourselves."

The Cardinals (2-2) expect a lot more from themselves than the six turnovers Kurt Warner was victimized for. Arizona trailed 34-0 at halftime as New York (2-2) got three Favre to Laveranues Coles TD passes and Darrelle Revis' 32-yard interception return for a score.

Arizona wide receiver Anquan Boldin was carted off the field after a scary helmet-to-helmet collision with New York safety Eric Smith in the end zone with 27 seconds remaining. Boldin was moving all his extremities on the field and was talking to his teammates, but was immobilized and taken to Mount Sinai Hospital in New York for precautionary reasons.

"He's alert," Cardinals coach Ken Whisenhunt said. "He asked to get up and the doctors wouldn't let him."

Elsewhere, Dallas and Denver were beaten for the first time, while Buffalo and Tennessee remained spotless.

Idle this week was another unbeaten team, the Giants (3-0), along with Indianapolis, Seattle, Miami, New England and Detroit.

Redskins 26, Cowboys 24

Jason Campbell threw two touchdown passes and Clinton Portis ran for 121 yards in Washington's last regular-season visit to Texas Stadium; the Redskins (3-1) won for only the second time in the last 13 trips.

Chiefs 33, Broncos 19

Larry Johnson ran for 198 yards and two touchdowns, and the Chiefs took advantage of four Denver turnovers, snapping a club-record 12-game losing streak.

Nick Novak kicked three field goals for the Chiefs (1-3), who did not seem to be out of danger until Tony Gonzalez snared a 10-yard touchdown pass with 12:40 to go.

Bills 31, Rams 14

At St. Louis, the Bills moved to 4-0 for the first time since 1992, the middle of its dominant AFC years.

Jabari Greer's 33-yard interception return on the first play of the fourth quarter was the go-ahead score as Buffalo handed St. Louis (0-4) its 17th loss in the last 20 games.

Titans 30, Vikings 17

At Nashville, Tenn., rookie Chris Johnson scored two touchdowns, the defense forced four turnovers that Tennessee turned into 21 points, and the Titans improved to 4-0 for the first time in franchise history.

Bears 24, Eagles 20

At Chicago, Alex Brown stopped Correll Buckhalter at the goal line late in the game, and the Bears (2-2) hung on after a pair of head-scratching losses that raised questions about their killer instinct.

Kyle Orton was 18-of-34 with 199 yards and a career-high three touchdowns — all in the first half, as the Bears built a 21-14 lead. Orton threw for just 25 yards in the second half as the Bears nearly gave away the game.

Chargers 28, Raiders 18

At Oakland, Calif., Darren Sproles' long kickoff return set up Nate Kaeding's go-ahead 47-yard field goal with 1:51 to play, and LaDainian Tomlinson sealed the Chargers' 10th straight win over their AFC West rivals — and the possible end of coach Lane Kiffin's tenure — with a 41-yard TD run.

The streak by San Diego (2-2) is the longest any team has held against Al Davis' once-proud franchise.

Buccaneers 30, Packers 21

At Tampa, Fla., Derrick Brooks had one of three interceptions of Green Bay quarterback Aaron Rodgers and also forced a fumble that Jermaine Phillips returned 38 yards for a touchdown.

Rodgers threw two touchdowns to Greg Jennings, who had six receptions for 109 yards for Green Bay (2-2), but was sacked three times and left for one series with a shoulder injury midway through the fourth quarter.

Jaguars 30, Texans 27, OT

At Jacksonville, Fla., Josh Scobee won a second straight game for the Jaguars, with plenty of help from David Garrard again. Scobee's 37-yard field goal in overtime won it. Scobee hit a 51-yarder with 4 seconds remaining last week to beat Indianapolis 23-21.

Panthers 24, Falcons 9

At Charlotte, N.C., Steve Smith's first touchdown following his two-game suspension was part of a dominating day. Jake Delhomme was mistake-free, Smith and Muhsin Muhammad combined for 243 yards receiving and two scores, and Carolina (3-1) shut down the league's top rushing unit.

The Panthers held Michael Turner, who came in as the league's top back with 336 yards rushing, to 56 yards on 18 carries.

Saints 31, 49ers 17

At New Orleans, Deuce McAllister carried 20 times for 73 yards and had a 10-yard reception to convert a third down, giving the Saints (2-2) the credible power running threat they needed to open up deep throws for Drew Brees.

Brees was 23-of-35 for 363 yards and three scores.

Browns 20, Bengals 12

At Cincinnati, Derek Anderson threw a 4-yard touchdown pass to Braylon Edwards that put the Browns (1-3) ahead to stay in the fourth quarter. With Brady Quinn ready to take over if Anderson struggled again, Anderson went 15-of-24 for 138 yards with a touchdown and an interception.
