A quick-hit Raiders practice update from Wednesday morning's workout: Although back at the team hotel four hours after he was injured, running back Mike Goodson did not join his teammates at practice.
A CT scan and MRI showed no damage after a blow from linebacker Philip Wheeler sent Goodson to the hospital in an ambulance Tuesday afternoon.
Allen had no timetable on when Goodson would return, saying, "We're going to wait until he's fully healthy before we put him out there.''
Although Allen wouldn't rule him out of the Dallas preseason opener on Aug. 13, it would appear the bulk of the work will go to first-year player Lonyae Miller out of Fresno State.
Taiwan Jones, competing with Goodson to be the primary backup, remains out with a hamstring strain.
Rashawn Jackson, primarily a fullback, took reps as the third string tailback. After six straight practices in pads, and with increased soreness and some injury issues, Allen had the Raiders practice in shorts and shells heading into Thursday's day off.
Although the pads were off, Allen was stressing tempo and playing at full speed, although without the contact. Wide receivers Denarius Moore and Eddie McGee worked with the athletic training staff along with Jones. All have hamstring strains. Also not practicing were defensive tackle Richard Seymour (knee), linebacker Aaron Curry (knee), defensive end Jack Crawford (foot), place kicker Sebastian Janikowski (illness) and punter Shane Lechler (knee).
Lechler was spotted walking out of the field Tuesday night with a wrap on his left, or plant leg. Linebacker Philip Wheeler continues to excel on pass defense. In one sequence, he broke up a medium depth pass intended for Marcel Reece then stole a Carson Palmer post pattern intended for Brandon Myers. Backup quarterback Terrelle Pryor continues to struggle with his passing, with occasional overthrows as well as throws where the nose of the ball leads to throws into the turf.
