ALLEN PARK, Mich. – Detroit wide receiver Charles Rogers will miss the rest of the season after breaking his collarbone for the second straight season.

The No. 2 pick in the 2003 draft was injured going for a pass Sunday in the first quarter of the 20-16 victory over the Chicago Bears. X-rays revealed a fracture near the one he got last year during a bye week practice.

Rogers played only the first five games of his rookie season because of the injury, catching 22 passes.

He will have surgery later this week or early next week and will be placed on injured reserve, coach Steve Mariucci said Monday.

Broncos

Cornerback Lenny Walls could miss up to a month after dislocating his right shoulder in Denver’s opener.

Walls, who started all 16 games for the Broncos last season, played the nickel spot in their 34-24 win over Kansas City on Sunday. Coach Mike Shanahan said it looked like a four-week injury, but could be less.

Buccaneers

Wide receiver Joey Galloway will miss four to six weeks after aggravating a groin injury.

Coach Jon Gruden said the oft-injured 10th-year pro, obtained in an offseason trade from the Dallas Cowboys, has a tear in his left groin that is more serious than the Bucs anticipated.

Galloway missed most of the preseason with a sore groin and aggravated the injury in the first half of Sunday’s 16-10 loss to the Washington Redskins. He came up limping turning to try catch a pass that glanced off his hands in the end zone, costing the Bucs a touchdown.

The loss is especially damaging because the Bucs also are without last year’s leading receiver, Keenan McCardell, who is holding out for a new contract after catching 84 passes for 1,174 yards and eight TDs last season.

The team is also missing Joe Jurevicius, recovering from back surgery after missing most of last season with a knee injury.

Seahawks

Running back Shaun Alexander has a bone bruise on his right knee, but could play in this week’s game at Tampa Bay.

“It might be a week or two,” coach Mike Holmgren said. “There’s a chance he can play this week. We’ll just have to see how it goes.”

Said Alexander: “I’m a fast healer. I’ll be all right.”

49ers

Starting QB Tim Rattay has a separated right shoulder and Ken Dorsey, the former University of Miami star and a seventh-round draft pick in 2003, will start in New Orleans on Sunday unless Rattay’s injury heals much more quickly than expected.

Rattay was injured while getting sacked by Atlanta’s Rod Coleman in the second quarter of the 49ers’ 21-19 loss to the Falcons on Sunday. Dorsey took over and led two scoring drives in his first NFL action. But after Dorsey got a stinger in his right shoulder late in the third quarter, Rattay returned and led three lengthy drives, throwing two touchdown passes.

But an MRI exam on Monday revealed a serious shoulder separation for Rattay, who has struggled with a groin injury and a sore forearm during the offseason and training camp of his first year as the 49ers’ starter.

Ravens

Ethan Brooks, who replaced Jonathan Ogden at left tackle in Baltimore’s 20-3 defeat at Cleveland, will miss at least two weeks with a sprained knee ligament. The Ravens hope to have Ogden, who missed Sunday’s game with a sprained knee, back for this week’s home opener against Pittsburgh.

Vikings

Michael Bennett’s knee is feeling better after a workout, but Minnesota coach Mike Tice probably will sit his starting running back again next Monday in Philadelphia.
