Cornerback DJ Hayden won't the only Raider unable to practice on Friday. Head coach Dennis Allen said on Thursday that several other players will join him on the sideline.
Tight end Nick Kasa (hip flexor) and guard Lucas Nix (knee) will join Hayden on the physically unable to perform list. Safety Usama Young (quad) and cornerback Keith McGill hurt themselves during Thursday's conditioning test -- everyone passed, by the way -- and are expected to go on PUP, though Allen said that hasn't been ultimately determined.
Defensive end C.J. Wilson (hamstring) and defensive tackle Stacy McGee (thumb) will be placed on the non-football injury list.
Defensive lineman Antonio Smith, who missed the offseason program with an unspecified offseason surgery, is fully healthy and ready to practice.
