NFL injury report: Fargas out; McFadden takes over

The Oakland Raiders lost running back Justin Fargas to injury. That opened the door for a big game by rookie Darren McFadden.

Fargas injured his groin midway through the second quarter when he tried to run a pass route down the sideline. Fargas pulled up lame well before JaMarcus Russell's pass arrived, then fell to the ground holding the inside of his leg.

Fargas stayed on the ground for a few seconds, then limped to Oakland's sideline. He had 43 yards on nine carries before the injury after leading the Raiders with 97 yards on 18 carries against Denver last week.

In his place, McFadden ran for 164 yards and a touchdown in Oakland's 23-8 win.

Chiefs quarterback Damon Huard didn't play the final three quarters after suffering what the team called mild head trauma. He was already filling in for Brodie Croyle, who separated his shoulder against New England last week.

The 12-year veteran was in for Kansas City's first two series, but didn't return after throwing an interception late in the second quarter.

Huard finished 2-for-4 for 19 yards and was replaced by Tyler Thigpen.

The Bears lost return specialist Devin Hester after he was carted to the locker room with an apparent rib injury during the third quarter of the Bears' 20-17 loss to Carolina.

Hester grabbed the left side of his rib cage after a kickoff return and walked to the sideline. He was then taken inside for treatment.

Hester set an NFL record last season by returning four punts and two kickoffs for touchdowns. Carolina held him to three kickoffs returns for a 21.7 average and two punt returns for 9 yards before the injury.

Cincinnati lost tight end Ben Utecht hurt his chest on the Cincinnati Bengals' first play of the game Sunday and left the field on a cart.

Carson Palmer's pass went off Utecht's hands as Tennessee linebacker David Thornton hit him in the chest. Utecht lay on the field for several minutes, then got up slowly. He was wobbly as he walked off the field with assistance, then got onto a cart and was taken to the locker room.

In Seattle, one wrong step in pregame warmups ended Seneca Wallace's day. One big hit early in the first quarter Sunday sent Logan Payne to the sidelines too, only adding to the almost comical injury situation facing the Seahawks receivers.
