TEMPE, Ariz. – The Arizona Cardinals are turning to yet another quarterback, this time rookie John Navarre.

The seventh-round draft pick from Michigan, who never has taken a snap in an NFL regular-season game, will make his debut Sunday when the Cardinals visit Detroit.

Coach Dennis Green announced the move Monday, benching Shaun King after two starts and going with Navarre over Josh McCown, who had the job for the first nine games.

“Isn’t that the American dream?” Green said. “Isn’t the American dream all about opportunity? If one guy hasn’t worked out and another guy hasn’t worked out, why shouldn’t the other guy get a chance? And I’ve got a lot of confidence in him. I think he’ll do fine.”

Green said McCown would be the backup, with King demoted to third string after the Cardinals (4-7) scored just 13 points in his two starts.

“Quick hook? Yeah,” Green said. “Tough business, and you don’t have to apologize for it being a tough business.”

Broncos

Cornerback Lenny Walls was lost for the season after he dislocated his shoulder for the third time in the last 10 weeks. Walls, who hurt himself Sunday in Denver’s 25-24 loss to Oakland, will have surgery and be placed on injured reserve.

Walls started for the Broncos (7-4) last year, but lost that spot after he hurt his foot on the first day of training camp. He returned for the season opener, but missed four games this year with the various shoulder injuries.

Browns

Linebacker Andra Davis will miss the remainder of the season after tearing a ligament in his left knee against the Bengals.

The Browns will place Davis on the injured reserve list, making him the 13th player on it during a season of costly injuries for Cleveland (3-8), which has lost five straight games.

Davis tore the medial collateral ligament in his left knee in the third quarter when Bengals tight end Tony Stewart rolled up on his leg. The injury is to the same knee that Davis had repaired when he played at Florida.

Vikings

Onterrio Smith, not former Pro Bowler Michael Bennett, will be Minnesota’s starting running back for now.

“We’ll try to define a role for Mike,” coach Mike Tice said, “but I think right now we’ll try to ride Onterrio and see how he progresses down the stretch.”

Smith, in his second year out of Oregon, racked up 421 combined yards in the Vikings’ first three games before serving a four-game suspension for violating the NFL’s substance abuse policy. He had a season-high 20 carries for 72 yards in Sunday’s 27-16 win over Jacksonville.

Bennett, a starter in four of the Vikings’ previous five games, was in for a handful of plays Sunday and didn’t carry the ball. He has gained just 89 yards on 27 carries since returning from a sprained knee Oct. 24.

After an ankle sprain, rookie Mewelde Moore also could be back in uniform this week at Chicago, though he likely would be limited to kick returns.

Colts

The Indianapolis offense has been playing at a record-setting pace. Not even a makeshift offensive line has been able to slow down the Colts (8-3).

As Peyton Manning challenges the NFL’s single-season touchdown record, Edgerrin James tries to complete his best season as a pro, and three wide receivers are on pace to top 1,000 yards, the Colts are again being forced to adjust their line.

This week they will likely play without starting center Jeff Saturday, who injured a tendon in his right calf and is expected to miss three to four weeks. Rick DeMulling will likely slide over from left guard to replace Saturday.

“I played a little there during my rookie year, during the preseason and a little bit in practice,” DeMulling said. “Jeff does it, so it can’t be too tough.”

The Colts played the last two weeks without their two starting guards, DeMulling and Tupe Peko, and Indianapolis is again revising its plans to replace Saturday, who has started 75 straight games at center before going down in the third quarter of Thursday’s 41-9 rout of Detroit.

Bills

Travis Henry might not have broken a bone in his right leg, as first feared, according to coach Mike Mularkey. The team is conducting further tests on the running back and should have a more definitive diagnosis when the Bills (5-6) return to practice Wednesday.

Henry, the backup to Willis McGahee, was hurt four plays into the team’s opening drive in a 38-9 win at Seattle on Sunday. Linebacker Isaiah Kacyvenski tackled Henry and rolled up on his leg following a 5-yard reception.

Clutching the back of his leg, Henry lay on the field for several minutes before needing help to limp to the sideline, where he was carted to the locker room.

It was the same leg Henry hurt in Week 11 last season, a hairline break to a bone just above his ankle. Henry did not miss a game because of that injury, and went on to his second consecutive 1,300-yard rushing season.

Titans

Tennessee officially ended safety Tank Williams’ season by placing him and rookie safety Justin Sandy on injured reserve, allowing them to activate defensive end Bo Schobel and cornerback Tony Beckham off the physically unable to perform list.

Beckham tore his right ACL in April, while Schobel broke a bone in his right foot in June.

Coach Jeff Fisher said Schobel will be included in the defensive line rotation, while Beckham might be questionable.

“It’s kind of a free move for us,” Fisher said, noting Williams tore his left ACL on Nov. 14 and Sandy broke his right ankle on Nov. 21. “We need his legs on the practice field, so we have the space. We’ll continue to watch Tony and push him. He’s doing well right now.”

The Titans now have six players on injured reserve.

Giants

Defensive end Chuck Wiley will miss the rest of the season with a knee injury.

Wiley, who was signed earlier this month after Michael Strahan and Keith Washington were lost for the season with injuries, tore the anterior cruciate ligament in his left knee in Sunday’s game against Philadelphia.

Defensive tackle Norman Hand had an MRI on Monday to examine the extent of a groin injury.

Coach Tom Coughlin said the Giants would probably have to sign another lineman for this weekend’s game at Washington.

Jaguars

Despite a second straight loss, coach Jack Del Rio had two positives to talk about: Denver and Baltimore also lost.

“It’s nice to see Denver lose; it was nice to see Baltimore lose – those teams that are with us in this pursuit of the wild-card spot,” Del Rio said. “We all have a lot of football to play and anything can happen. But I think it’s great that we can still talk about that in late November. It hasn’t been like that around here for a while. It wasn’t like that last year.”

It might not be like that much longer, unless the Jaguars (6-5) find a way to score more. Jacksonville was held to just one touchdown for the second consecutive week in a 27-16 loss at Minnesota on Sunday.

Only Arizona, Chicago, Miami and Washington have scored fewer points than the Jaguars.

“We just plain need more points,” Del Rio said. “It’s tough to win with just one touchdown.”

After a 3-0 start, the Jaguars have faded fast. Now, they are two games behind Indianapolis in the AFC South and face streaking Pittsburgh (10-1) on Sunday night. But because the Broncos and Ravens also lost, Jacksonville remains just a game back in the crowded chase for the wild-card spot.

“Anytime somebody ahead of us can lose, it’ll help,” cornerback Dewayne Washington said. “But it isn’t going to help us if we don’t win. We’ve got to win games. You hate to rely on another team in this league. We don’t want to get into that.”

Bengals

Running back Chris Perry will get more medical tests this week for abdominal pain. Perry, the 26th overall pick out of Michigan, has appeared in only two games and carried the ball twice for 1 yard. He also has three catches for 35 yards.

“Chris had a good workout yesterday before the game and felt good,” Lewis said Monday. “We’re going to do some other scans and tests on him over the next two days just to see if there’s anything else that we can find that’s hindering him. He still has some discomfort at times.”

The Bengals (5-6) were hoping to use Perry as a complement to Rudi Johnson, who topped 1,000 yards for the season on Sunday. Instead, Perry hasn’t been able to make it onto the field.

He strained a hamstring in the final preseason game and didn’t appear in the first three games. He made his debut in Pittsburgh on Oct. 3, catching two passes for 24 yards. A week later in Cleveland, he caught one pass for 9 yards and carried twice for 1 yard.

During practice the next week, Perry aggravated sore abdominal muscles during practice. He hasn’t played since.

Redskins

The score is 946-945, and Clinton Portis is losing.

The running back, conspicuous by his absence in another feeble effort by the offense, has fallen a yard behind the Denver Broncos’ latest running back from nowhere in the unofficial race to shake down the teams’ blockbuster offseason trade.

Out in the Rockies, Reuben Droughns has come on strong to follow the tradition of Terrell Davis, Olandis Gary, Mike Anderson and Portis as the Broncos challenge for a playoff berth.

Back east, Portis is getting marginalized in a struggling offense for a team going nowhere.

Portis had just six carries for 17 yards when the Redskins (3-8), the lowest scoring team in the NFL, lost 16-7 to Pittsburgh on Sunday. He was on the bench for long chunks of time, including the entire 13-play drive that resulted in Washington’s only touchdown. Backup Ladell Betts gained 34 yards on eight carries, including a 26-yard scamper that marked the team’s longest run from scrimmage since opening day.

“Certainly we’d love to have Clinton get his full share of carries,” coach Joe Gibbs said Monday. “But the last two weeks we’ve been against very good defenses. Looking back on it, would you like to run the ball more? Yeah. Did we think we could run the ball down the field against Pittsburgh? No. We certainly want a mix in there, but it’s my responsibility to get us more runs in there.”

This is hardly what the Redskins envisioned when they traded four-time Pro Bowl cornerback Champ Bailey and a second-round draft pick for Portis, who rushed for 1,500 yards his first two NFL seasons. Portis signed an eight-year, $50.5 million contract.
