Former Hog Darren McFadden will miss Raiders preseason opener against Cowboys

NAPA, Calif. (AP) - Oakland Raiders running back Darren McFadden

will miss the preseason opener against the Dallas Cowboys with a

sore left hamstring.

McFadden injured the hamstring in the first practice last

Saturday and has sat out practice since. He says he wants to make

sure he's completely healthy before returning to the field so the

injury doesn't linger all season.

McFadden has been plagued by various injuries since being

drafted fourth overall in 2008. He has run for 856 yards in 25

career games.

The Raiders also are expected to be without receivers Chaz

Schilens, Jacoby Ford and Paul Hubbard, quarterbacks Bruce

Gradkowski and Charlie Frye, fullback Luke Lawton, and defensive

end Jay Richardson.
