White (quadricep) won't practice Wednesday, Paul Gutierrez of ESPN.com reports.
Alexander Mattison (ankle) was also sidelined for Wednesday's practice, making the statuses of both backs worth tracking as Sunday's game against the Broncos approaches. For now, the healthy running backs on the Raiders' active roster are Ameer Abdullah and Dylan Laube. White carried five times for nine yards across 21 snaps in this past Sunday's 34-19 loss to the Dolphins before exiting with the quad injury.
