McFadden out with broken orbital bone

NAPA — On the day the Oakland Raiders were supposed to be able to see their whole team practice for the first time this training camp, they were missing one of their most important players.

Star running back Darren McFadden was sidelined a day after breaking an orbital bone in his face and is expected to miss a couple of weeks, according to coach Hue Jackson.

McFadden left practice early Wednesday with the injury. He delivered a hard block on linebacker Quentin Groves in one drill, but Jackson did not say if that caused the injury.

"He'll be fine," Jackson said. "We'll get him back out here and keep on rolling."

After struggling his first two seasons, McFadden had a breakout year in 2010. He led the team in rushing with 1,157 yards, added 507 yards receiving and scored 10 touchdowns last season.

He finally delivered the big-play threat the Raiders had been waiting for since picking him fourth overall in the 2008 draft, leading the NFL with 14 carries of at least 20 yards.

The Raiders are short-handed at running back with rookie Taiwan Jones and veteran Michael Bennett also hurt, and Michael Bush waiting to sign his restricted free agent tender.

While McFadden was Oakland's biggest playmaker on offense last season, that role early in training camp is being filled by rookie receiver Denarius Moore. The fifth-round pick out of Tennessee has been making highlight-reel catches almost every practice, with his best coming Thursday on a pass from Jason Campbell.

Moore leaped over Stevie Brown and Demarcus Van Dyke in the back of the end zone and did a good job getting his toes down inbounds for a touchdown catch that left teammates gasping and led to a celebration usually reserved for more meaningful scores in the regular season.
