Powers-Johnson (illness) was a limited participant in Wednesday's practice, Paul Gutierrez of ESPN.com reports.
Powers-Johnson still appears to be dealing with the illness that forced him to miss Las Vegas' Week 1 loss to the Chargers. His practice participation Thursday and Friday will provide a greater indication of whether he'll be able to make his NFL debut in Week 2. If Powers-Johnson is still unable to go Sunday, expect Jordan Meredith to serve as the Raiders' top backup guard.
