Reggie Bush's injured knee will keep him from hopping across the pond next week.

Bush will not travel with the Saints to London following Sunday's loss to Carolina, instead heading to Alabama to have his left injured knee examined.

Bush is expected to see Dr. James Andrews in Birmingham, Ala., coach Sean Payton said. The Saints believe Bush has injured the meniscus in his left knee and won't be able to play San Diego in Wembley Stadium next week.

"I think our plan is to have him evaluated in Birmingham, right from here, so he won't make the trip," Payton said.

Bush injured his left knee on a punt return late in the first half. He reversed field on his run, which ended when he stepped out of bounds on the Carolina sideline. He seemed to pull up a bit and favor his left leg after that.

Bush missed practice earlier this week with swelling in his left knee, but the Saints said the injury was not serious.

Bush had 55 yards on nine carries, caught one pass for 5 yards, and had a 3.5 average on three punt returns against Carolina.

Just 14 plays into his return from a separated shoulder, Brodie Croyle suffered yet another injury, this time a sprained right knee that sent him off the field in the second quarter against the Tennessee Titans.

The oft-injured Chiefs quarterback is likely done for the season with ligament damage and may have lost his already-tenuous hold on the job for good.

Croyle's disappointing history of injuries added a new chapter when two onrushing Titans defenders hit him on a pass attempt early in the second quarter, twisting his knee. He completed the 17-yard pass to Dwayne Bowe, but had trouble getting up and couldn't put any weight on his right leg as he hopped toward the sideline.

Croyle was replaced by Damon Huard after completing 9 of 10 passes for 63 yards. It was the fourth time in eight starts Croyle was injured.

Another special teams star got hurt when Chicago Bears kick returner and wide receiver Devin Hester injured a quadriceps muscle in the third quarter against the Minnesota Vikings and had to leave the game. It was not immediately known how Hester got hurt, but he did return the second half kickoff and was initially charged with a fumble before video review reversed the call and gave the ball to the Bears.

Rams running back Steven Jackson, who had 160 yards and three touchdowns in a 34-14 win over the Cowboys, pulled a quadriceps muscle in the fourth quarter just before coach Jim Haslett was planning to lift him.

Haslett said Jackson would undergo an MRI, but Jackson thought he'd be fine for next week's game at New England.

"It's a little tight," Jackson said. "I'm able to walk and I'm able to bend it, so that's a good sign."

Injury troubles kept mounting for the Cowboys.

Safety Roy Williams broke his right forearm for the second time in his first game back from the previous injury, and owner Jerry Jones said he'd miss the remainder of the season.

Williams, who has made the past five Pro Bowls, was hurt midway through the third quarter. It was not clear how he was hurt.

A jolting block by Pittsburgh receiver Hines Ward broke the jaw of Cincinnati rookie linebacker Keith Rivers, likely ending his season.

Ward knocked Rivers down on the fourth play of the Steelers' 38-10 victory. Rivers, a first-round draft pick, stayed down on the field for several minutes before walking off without assistance. Tests found the fracture.

Ward, a former Super Bowl MVP, is known as one of the league's toughest blockers. He wasn't penalized for the block against a player who is 2 inches taller and about 35 pounds heavier.

Steelers cornerback Bryant McFadden and safety Troy Polamalu got hurt on the same play in the fourth quarter. McFadden injured his arm and was expected to have tests. Polamalu lost his helmet while tackling running back Cedric Benson and was unsteady as he walked off the field. Neither returned to the game.

The return of tight end Jeremy Shockey and wide receiver Marques Colston from injuries not only didn't provide a boost to the offense, Shockey lost a fumble that led to Jonathan Stewart's 18-yard TD run in his first game back from hernia surgery. The Saints fell to the Panthers 30-7.

Buffalo backup linebacker John DiGiorgio hurt his right knee in Buffalo's 23-14 win over San Diego. DiGiorgio, a special teams standout, was injured on a punt return late in the second quarter. He was carted off the field, unable to put any weight on his right leg.

Also, Bills starting right guard Brad Butler strained his left knee early on and returned briefly, but ultimately was unable to finish.

Dolphins nose tackle Jason Ferguson left the game in the first quarter with a rib injury and didn't return.
